JD picked up a new daily driver.
Baseline before tuning
After
:bigtup:
Wow that’s just a tune? When I had my tbss tuned it was night and day so id imagine its the same for these things. I’m sure it will be a fun car for him.

Wow, who tuned it, and what do you think I’d get with a tune on the GTO?
It’s got a intake/cold air box on it and the tune.
The cars are also tuned from the factory to run on 87 octane which has a lot to do with any gains.
If you notice the section I posted this in…John Donovan tuned it he has been doing HP tuners for a while now.

I doubt a stock GTO would pick up anything like this see the above comment about 87 octane.
That’s awesome! Tup jd
thats kind of upsetting these things are only 280/260 cars from the factory Lol
Searching around they make usually make 280-300 on 87 octane stock
:tup:
Hells yes!! :tup: also, thumbs up to a no bull shit thread, upfront and no scamming for people who are not sponsors for the site. Good job John.
Awesome work John! Now let’s do some pulls in zhighway
gay 
nice :tup: I love these cars.
His first ls car and he already made that much more power. Congrats John, we all knew it was a matter of time before u took over the ls tuning in buffalo.
Turbociv should be posting this in a build thread. Dammit sherm
:tup:
Congrats that is nothing short of incredible tuning :tup: . You gained 70 rwhp & 72.4 lbs. ft of torque from 93 octane, cold air intake and tuning. You should post the results on the HP Tuners Forum, G8 Board, and LS1tech.com. Once people get wind of it you will be so busy tuning cars you will have to purchase another dyno just to keep up. Welcome to the big leagues
And he had built 1005hp car :tup:
thanks guys, might take her to the track to see what she can do tonight if the weather holds. im hoping for a low 13sec pass. but in this heat who the hell knows. ill start a build thread when I get the snail. 
Since you’re banned from LS1tech for scamming you might be unaware of how these things dyno.
Lots of them dyno 280-300rwhp stock
People make 320-330 rwhp on 87 octane tunes with a CAI.
This guy dynoed 382 with intake/tune/headers - https://www.youtube.com/watch?v=cCUY0qDTkBg
PatG 335 rwhp on 87 - No BS dyno test of Vararam CAI for G8 - LS1TECH - Camaro and Firebird Forum Discussion
Yeah banned because once you are a sponsor of LS1tech and then stop sponsoring them IB automatically bans your account.
Anyways long tube headers generally make an additional 25 rwhp and 25-30 lb. ft of torque. So this is :tup: no matter what. You should post if for him on LS1tech.com I am sure more than a few people will be impressed.
You should take this motor out, give it to me and put a 4.8 in if you’re turbo’ing
