So glad you had an assist on that engine identification...6.0 diesel would have been a horrible thought. I personally have a 2000 Chevy Silverado 2500 also with the 6.0 gas. It's all stock and original...to my knowledge. I am the 2nd owner and currently have just over 433k miles. Love it!
My 2016 crew cab Chevy 4x4 with the 6.0 gasser typically gets 9-10mpg in town. 14-15mpg on the highway. All stock (except muffler delete pipe) and unloaded.
Idk if you have your speedometer/odometer reset for the size of your tires compared to stock but if you don’t then you actually are traveling almost 15% (14.9%) further than your odometer says. So in this case you actually got 11.85 mpg. Not bad!
Yeh, it wasn't the most accurate test, but I got a lot of questions on what a 680 WHP truck gets. It's so hard to say because it doesn't get driven enough.
I just turbo’d my stock 2001 1500hd pickup. Last tank I averaged just under 12mpg. It’s on 32” tires and leveled so nothing crazy. Currently on about 12 lbs. it’s really hard to keep my foot out of it for fuel economy lol. Just a basic eBay setup, gt45, cast iron log manifold and stock cam still. Super happy with how driveable it is though.
My 95 Suburban is currently in the works for the same thing, only difference is hardware. Pulled the 6.5 diesel out of it (yuck) and dropping in a 5.3. Currently waiting on pistons and high stall converter. 4l80e of course and a short 14-bolt rear end already in the truck. Thinking maybe 12 psi would be a good healthy start? Lol
So don't your valve springs float at 16lbs? That's a bit of boost. I have read that on stock heads with factory springs they have issues after 12lbs. A screw is in my future, just have to figure out over all cost. I figure probably 4 grand would get me there.
So 10.3 x 34 gal tank with calibrated speedo for tires, cam, mods 11-12.0mpg x 34 = 374-408 on a tank. That still better than what I'm getting but could possibly get that with a light foot. BUT...adding a turbo would be more funner and damnit I want one so I still win! "Hello STS??..." lol
I'm not really getting it.. Is turbocharged trucks are better MPG? I have 2006, 6.2 Chevy 3500, and Im planning to turbocharged just for having better fuel consumption, I drive it on highways mostly so no rough acceleration, do you think it will help if I do?
The trick is keeping your foot out of it! It's tough because all the power you add! A turbo does make it more efficient but I don't know if it would pay for itself with the expense of the system and price to install it. That's why most new vehicles have a turbo or supercharger from the factory because you can make them more efficient.
@@slow_restoration thanks for your reply, indeed that what I was mostly thinking about, how hard you accelerate is really the trick 😜, however most of my friends have another opinion on that, but now you confirmed my thoughts. God bless you dear, I really like the work you did in your truck by the way.
excellent, did you use stock injectors, on my 2016 sierra they are 50 lb/hr @58 psi, it's also accepts e85 which is why they are rated at that, would you suggest getting in contact with nelson first and telling them the goals for the sts and then order the kit?
That’s turbo flutter, you actually don’t want that noise to happen because your blow off valve is workout efficiently enough to vent the pressure and stop it from spinning the compressor wheel backwards. The closer your put the bov to the turbo itself the better it works.
Debadge it. Too much junk hanging off of it. Clean sides and a bigger tire will make it look a lot better. The stock mirrors are hideous. The big sticker on the back window is throwing everything off.

Yeah, sometimes weird things come out! Nice, keep it going!

Damn that's better mpg then my 2017 3500 dually stock with the 6.0 gasser.,...I think my average is like 9.6mpg currently
10.31 is an excellent 1/4 mile time to shoot for in the turbo GMC!!!
Going to have to put it on a diet for that time! It's a goal though!

Thanks, it is calibrated to the tires. It's not dead on but close.
Such a bad ass truck! Best looking generation.
Thanks, I should probably update the look some!
Best body style ever made
thats actually super impressive for a cammed gas in a heavy duty three quarter ton lifted with giant ass tires.
I got the same truck with the 6in rough country kit runs nice love the truck
Thanks, nice!
10.3 MPG for mostly highway seems a bit low, but maybe it wasn't mostly highway? Extra idle definitely sucks the fuel on these 6.0 even stock.

Love that truck... I call dibs if it ever goes up for sale👌🏻
You never know! Thanks
Truck sounds really good
Thanks! Got to love a turbo!
Looks nice cleaned up!!
It still cleans up nice! Just don't always have the time anymore!
Awesome Sierra! Love the truck!
It's just an old truck, thanks!
Without the lift and offroad tires it do a good bit better

It has PAC .660 dual springs and a Texas Speed cam.
I missed that part lol
Nice truck. How would it do towing. What are your thoughts. Say 15k lbs.
It tows amazing, there're some videos already in the playlist about towing. Thanks for watching!
So 10.3 x 34 gal tank with calibrated speedo for tires, cam, mods 11-12.0mpg x 34 = 374-408 on a tank. That still better than what I'm getting but could possibly get that with a light foot. BUT...adding a turbo would be more funner and damnit I want one so I still win!
"Hello STS??..." lol
Had you speed corrected with gears or speedo calibration? This jacks your mpg if not
Yes it's corrected.
@7:08 i'm in heaven!!!!!!
You & me both. Love the old square bodies.

Do you still have this truck, would you ever be interested in selling it
I do still have it, everything is for sale for the right price.
just out of curiosity who did your tune and did you have to put in a different ECU or anything like that
Nelson performance did the tune, still stock ECU.
was Nelson able to do it remotely via email, and did you have to install a wideband o2 sensor for them to tune it?
They send a tuned ECU out and you swap it in your truck then send yours back as a core.
excellent, did you use stock injectors, on my 2016 sierra they are 50 lb/hr @58 psi, it's also accepts e85 which is why they are rated at that, would you suggest getting in contact with nelson first and telling them the goals for the sts and then order the kit?
How much did you spend on your tubo kit?
Did he say 6 liter diesel?
By mistake! 6.0 LQ4 gas.
Nice truck Very Nice..
Thanks, I like it!
6 liter gas? not diesel right?
Yes, gas iron block LS
if i put a turbo in my 2010 Silverado will it make the stutututut noise ?
That’s turbo flutter, you actually don’t want that noise to happen because your blow off valve is workout efficiently enough to vent the pressure and stop it from spinning the compressor wheel backwards. The closer your put the bov to the turbo itself the better it works.
Do you pass inspection? I wanna know cause I wanna do this
6 liter Diesel?
6.0 gas
So you didn't gap the rings and it's been fine?
No, the heads haven't been off yet! So far so good!
@@slow_restoration that's awesome because I've been considering turbocharging my truck but didn't want to pull the engine all apart to gap the rings
Its all in the tune! Parts failure is usually in running lean!
You said 6.0l diesel lol
It'd be like driving an eight track tape player..
What size injectors are you running.
60# Deatschwerks
What about your fuel pump. Thanks.
This truck has a Walbro 320 in tank but the new build is getting a Deatschwerks fuel system with there 400.
You’re running up to 16lbs with no ring gap??
Just what GM put in it! The meth helps cool things also.
I’ve seen 20+ lbs on stock gap.
What would be safe without?
Debadge it. Too much junk hanging off of it. Clean sides and a bigger tire will make it look a lot better. The stock mirrors are hideous. The big sticker on the back window is throwing everything off.
This is a very old video. The truck looks completely different now!
newer trucks 2015+ are garbage lol idk why people even buy that trash
