- In this episode of the 991 Build Series I talk about why I chose to ECU tune the car, arguments for and against, how to install the tune yourself, and my honest thoughts. Ultimately, is it worth tuning a naturally aspirated 911? This one is a little long, but stay until the end to hear my honest thoughts.

Loved this video! Exactly what I was looking for on the COBB 991.1 Code loads. Hopped on eBay right after watching and was fortunate to find an Access Port for half price. Snagged and installed three
days later (easy). The Op is right on the money in all regards. Car definitely pulls stronger, very noticeable. I only ever shift in manual with paddles and drive in Sport mode 90% Sport Plus 10% and this load gave me the firmer, solid shifts I was hoping for. 1 to 2 and 2 to 3 feel nice and firm with a solid “thunk”, no slipping. Downshifts also feel firmer. That occasional stammer in first when you go from stationary to full throttle is completely gone. Car just overall feels much better and I think it was worth every penny. Looking for excuses to go drive again!!! Thank you Andrew!
Thanks Rick! Really appreciate you watching and so glad you found it helpful. Enjoy your car’s new personality!
Excellent and informative video...so happy I discovered this channel.. Information appears well analyzed and thought out. Thanks so much!!!!
Thank you! I really appreciate you watching and am very glad that you find the information helpful, and the delivery engaging!
Great overview and walk through... Very informative. Time to tune my Turbo!
Awesome. thanks for the feedback and thank you so much for watching.
Another awesome video Andrew. FYI the behavior you describe in Sport + of PDK not shifting until redline, that’s normal behavior for 991.1 in sport+ and not a by product of the Cobb tune, this is mainly a track setting to keep you in the power-band while on the track.
Gotcha. Good to know, thanks for weighing in.
he's right. I have the same car and no tune.@@nineelevensouth
Very helpful. Thank you for the details and in depth review.
I’m so glad you found it helpful! Thanks for watching.
Awesome review!! I paid the 2g only cuz i bought it from RAC and they did the install before pickup. Definately livens up car! Crisp shifts, rev matching, hill hold, so much more
Thanks so much! I really appreciate you watching and am glad you found it so helpful
Very interesting - thanks.
Love it.. Great video!
Thanks!
Great video
Thank you! Appreciate the feedback.
Great video Andrew! Love the graphics! Sure to add to the "literature" for 991.1 owners considering a tune. Well done!
thanks man! appreciate you watching!

@@geffcampagnolo6363 Hi Geff Did you Tune your Porsche 911.1 with Cobb ?
I did my 991.2 Targa with Cobb. Stage 2 with Soul cats.
Love the video series. One thing that’s overlooked in tuning a 991.1 is the way the car makes power. On a stock tune there is a dip in power when the car comes on cam. This can be felt and seen on the dyno. A tune almost eliminates this. Even if the car made no more power(it does) this alone still enhances the way the car makes power to make it worth it.
Very good point. Even Cobb's OFT tune has that dip, only way to somewhat remove it is via a custom tune (is what I am told and have seen).
@@kam1996 gotcha - I have FVD and its instantly noticeable. I didn't think the tunes would be vastly different in this regard.
Bad ass video. Thank you
Thanks! I really appreciate you watching and hope that you found it helpful
i have this and love it. I've also put in long pipe headers - high flow cats and the combination improves the performance and sound. I've had a custom tune to take advantage that as well, that's deployed through the Cobb device. As you probably know, the ECU can be restored to factory anytime. PM me if interested, as I've also done a couple of other performance mods that maybe of interest to you.
Awesome. Thanks for sharing!
This was very helpful understanding Cobb tuning. I just discovered your video's and really appreciate your opinion and detail oriented approach to mods. I just got a 991.1 after owning every variation of the 997 so I'm a new to this gen 911.
Did you sell your 993? It's stunning!
Awesome. Thanks so much for watching and for commenting. I'm glad you found the videos helpful. I did sell the 993. Was hard to part with but I love doing these projects and it was onto the next build..
I have the same tune+PDK tune in my 991.1 GTS and agree with your take. Absolutely worth the upgrade considering the cost. I did go with the sequential PDK which gives you a lot of "manual" properties
Awesome! Thanks so much for watching and for sharing your experience. I feel like a lot of people automatically assume there’s no reason to tune an NA engine so I wanted to make this video to provide a real review from a real owner as opposed to the typical forum “bandwagon” effect.
@@nineelevensouth I have coupled mine with another much-hated/debated item, the newest version of Sprint booster. For around $250 you cant ask for a better improvement in throttle response. Give it a shot, you will NOT be disappointed as long as you keep your expectations in check and know that its just to fill the gap between Cobb tune and instant throttle perfection.
@@kam1996 Hmmm. interesting. I am considering headers and IPD next. Have a link to the sprint booster?
@@nineelevensouth Headers and IPD + a custom tune will surely wake this car up. I have it on good authority from a Porsche race shop that even the N/A GTS with its improved intake has a choke point and should be opened up. Do all the hardware and then find a decent custom dyne tune shop. You an get real (Vs promised) 430-440 HP out of your 3.8 no problem.
@@kam1996 awesome! Thanks
Very well done! Exactly what I was looking for. I just purchased a 2014 "S" cab and was looking for a cost-effective upgrade path. I am not much into aftermarket mods and the impact on resale, so this is definitely a path I will explore. Can anyone clarify if the "reverse shift stalk" means what I hope it does? I have an e46 M3 with SMG and I completely agree with BMW in terms of which way you should shift under power. Pulling back on the shifter when aggressively accelerating, and push forward when braking (for cornering) ... I have been doing this for over 12 years now and I am afraid to try it in the 991.1... Is that what it means? And is there a replacement plate for the shifter face to reverse the stamping... if that is what all this means?
Thanks! Appreciate you watching and glad you found it so helpful. In terms of the shift stalk - the way mine works is that "up/forward" shifts up a gear and "back/downward" shifts down a gear. So, the opposite of what you describe. I believe the COBB device allows you to change this to either way, depending on which map you are running. That said, changing this cannot be done independently in any map. Certain PDK maps have the direction a certain way. I would check their website or call them for more detail.
Great video, I was waiting for this one.
Would you suggest getting a tune if you have a manual? I'm trying to decide Cobb vs. Eurocharged vs. Stock.
Thanks for watching! I would say yes. I have had this tune on the car for a couple of months now, and have driven the car in all kinds of settings (in town, straight open roads, mountain twisties) and would say I drive with the paddle/floor shifter 75%+ of the time. So, if you have a manual I think you will still really enjoy the personality change and the extra, more linear power the tune will provide. Is it nice that with PDK the car can also drive much more aggressively in the various automatic modes? Yes. But that is not all there is to this tune by any means. Hope that helps.
Thanks for the response. What's your take on an OTS type tune vs a custom tune?
@@controlone For the average driver, OTS is probably more than adequate. That said, with the COBB tune you can have both. You can load something OTS, drive a bunch with the device connected and use the built in data logging, and then take that data file to one of many certified custom tune shops around the country (info on their website) for them to write one for you exact to your vehicle and driving style.
@@nineelevensouth very cool, didn't realize that was an option.
I guess I'll start stalking the forums to find a deal like you did!
@@controlone awesome. Good luck!
Q: Have you considered adding the DSC box? Would love to see that video...
I have added DSC. Will have a similar overview, install, before/after for that in the next couple episodes of the Build Series. Stay tuned!
@@nineelevensouth I have installed the DSC, COBB Tune, and getting ready to add an AWE Switchpath exhaust. I already have IPE Headers, so looking forward to my project this weekend.
@@meroliveria4652 awesome! Sounds like an incredible setup!
I've got Cobb and DSC and they work flawlessly together...
Great video, i just subscribed to your channel. I would like to know if you would suggest a cobb on my 991.2 turbo, its a 2017 and has 540hp stock. Cobb advertises 100 hp gain. Another concern i have is if it will void my warranty which ends 2023.Thanks.
Awesome. Thanks for subscribing. As you point out, theres way more HP to be gained with a .2 tune. So for that reason I would probably recommend it. Keep in mind that the tune w PDK for the .2 is a bit more expensive ($3k retail) so you'll have to weigh that piece in terms of ROI. In terms of warranty - "technically" it voids the warranty. But the beauty of the COBB Accessport device is that you can "flash" the ECU back to stock in like 15 mins. So if/when you need to take it to the dealer you can remove the tune easily, then just reinstall in 15 mins after. I would probably reach out to COBB to confirm, but that's my understanding.
@@nineelevensouth hey thanks for the quick response, yeah i know its about 3k but if you really get 100 hp for 3k i think its pretty good bang for the buck, can't really find any reviews on youtube about it, and on rennlist i get mixed comments on it. Concerning the warranty, i heard that even if you flash it back to stock porsche somehow still know when they hook it up back to their computer, not sure how true that is. Keep posting these awesome videos.
@@dinster762 I would agree
Awesome video. Love your attitude and the style in which you present the facts. I think this may be the only video that actually shows the driving part. Like to see how it does on my 17 991.2 base Carrera. My service advisor says the "factory" can see the upgrade even when you flash back. They will usually never say anything unless you have a warranty problem then they will say you have modified the ECU. I think the turbo cars get a bit of extra boost and try to eliminate turbo lag. Kind of turns my base Carrera to a Carrera S:) Anyone else try a 991.2?
Awesome video and We have up to 108 octane in Scottsdale and that would be helpful to try 93 or 95. Standard ECU saw no difference on higher octane, heard the ECU has to recognize the different octane. Keep up the great videos.
Thanks so much for the thoughtful comment and for watching! Glad you found the video helpful. Usually ECU tunes provide tons of benefit on turbo cars so I think you will see the same.
Nineelevensouth, Do you think the Cobb tune will help the base Carrera 3.4L engine?
Definitely
I'm thinking of just the ECU and not the PDK. What do you think. I am going to get most of the benefits from increase of boost. I tend to get 11 psi now, do you know what the new boost will be? I have heard around 17psi.
Not sure on the turbo engine stats as mine is NA
@@nineelevensouth Did what you recommended and did the tune. Took a while to learn I think. Now it is amazing. It is like a different car. Thanks for the great advise. Love it now.
Can not find info about if the device should be attached to the car all the time, or can be removed after you did tuning?
Removed after tuning
Whuups...22:50 police car
One other thing, can the Cobb Tunes be removed if need be? You mentioned unmarried....let's say a guy has a CPO car....the dealer won't be real happy with a sport tune....would need to unmark before going into th dealer I would think. May have to u marry before going in for the CA bi-annual emissions check.....
Yes. That is one of its biggest advantages. Just plug in the access port device and in about 10-15 mins you can reset back to factory and remove the tune.
I think it was very ironic that at 20:50 when you said "alot of people ask me...are you gonna feel 30 HP?...look, for what it's worth - I'm gonna say YES" (and then immediately you can see the police car drive by).
Ha! I know right?! Glad you caught that too
Does this void any type of warranty
Technically speaking, yes. But you are supposed to be able to “de tune” the car easily and to the point where Porsche can’t tell. That said, most of the people I know wait until out of warranty/CPO period to add this
@@nineelevensouth excellent, thanks
Hasn't been that long since you posted this, but are you still enjoying the benefits? Any additional mods? Settled into one tune? And are you ready to sell it to me? HA.
I love it. Settled on the 93 octane ECU map and the sport PDK map. Hard to imagine the car without the tune at this point. Def keeping it on.
@@nineelevensouth Good to know. Might have to bite the bullet during the Cobb Black Friday sale... these things are tough to find used. Thanks!
Pretty sure sports plus requires manual shifting on stock cars
Hmmm, good to know. Wasn't aware.
@@nineelevensouth Did you never try it out pre the cobb tune?!
@@andrewcampbell7030 I think I have always shifted manually with the paddles anyway in sport plus. Not sure I ever tried automatic, just with sport.
@@nineelevensouth I always assumed sport was more aggressive but automatic, sport plus was more aggressive again but manual (it won’t change gear unless you do it). That’s how I use it anyway!
@@andrewcampbell7030 I have driven mine on automatic Sport Plus and it works well so long as you are driving aggressively at the higher RPMS. It will shift automatically at speed. That's what it is designed to do IMHO.
