Good info on this, things I didn’t know about like the JB4 not kicking in until later in the RPMs. I think I’m leaning towards FEMTO after watching your vid
Yeah it does improve 0-60 times as well, but since I’m RWD the car doesn’t hook the best. I’ve heard Dahler is more smooth, but JB4 has more options like being able to run E85
@@sundeepm3 oh yea I had a RWD now I have the xdrive. RWD legit caused my crash.. thing went sideways into a fence. Lol. But yea, the dahler is 1k more expensive then the jb4 so I think the jb4 is the route to go. For the e85 do u need just the jb4 or do u need to install a flex fuel kit to be able to run e85.
@@G82Watts Yeah for the cost better off doing Femto instead of Dahler. You don't need a flex fuel kit if you follow the E content description on the map
I first had the JB4 and had a few drive train malfunctions which was annoying. Took it off and put on the Racechip. I can honestly say, the Racechip felt more linear and consistent. I gave the JB4 another try and the RC felt better. I did a log with the Racechip and it looked cleaner than the JB4. Zero throttle closures
@@markmartinez8000 Nice! I’ve been lucky without any issues on mine Map 2 93. Heard mixed reviews about the racechip that it doesn’t feel as aggressive

Yeah an ECU flash tune will always be better than a piggyback tune. I’d advise Femto if you don’t mind shipping out the ECU and the extra costs
@@sundeepm3 ya I don’t mind shipping it out, I’ve got a MK7 GTI I can drive while I wait. And I agree custom tunes will always be better.
Thanks for the great videos. I've been thinking about adding the JB4 too.
Anytime appreciate the support! Definitely worth adding the JB4, opens the car up
@@sundeepm3i would like to add a jb4 on my m340i but im not sure adding more boost to my car without adding gas thats what a real tune do
@@b58forever You can run the Map 2 tune, which is made for 93. It’s conservative so made for that fuel
Custom tune gives you more power gains and jb4 can cause issues. Stay stock until you can do a proper unlock
Did you notice any difference in exhaust being louder or more burbles?
Not really any difference in loudness burbles. I do have a single midpipe and valve controller which increased both of those a lot more
Does it improve 0-60 at all, also price aside what do u think is the best piggy back option
