Roastin Performance LLC
I referred my buddy who has a vette that was running rough after 2 different shops dyno tuned his vehicle, 800 or 1000 plus bucks later! !! I sent him to John at roastin performance who I previously worked with a couple years back. My friend is thrilled at how well the car drives. I can say that the vette is waaaaay faster now! He said he is getting 3 to 4 mpg better mileage as well. Anyone else with a modified car you need to see John. He will get you straightened out and running flawless.

Sentiment Analysis
John is very knowledgeable and I say that having some knowledge of how all of this works so it’s not coming from someone that “thinks” the tuner knows something just because the tuner fixed something they couldn’t.
The Tahoe was incredibly frustrating due to all the false info from keyboard warriors out there, every step of the way John was correct with all his advice to get it straightened out.
The Terminator X was tuned with Holley software, transmission tuned with H Ptuner, TCM with PCS software.
I ended up going to my go-to for my Trans Am and had him tune my 2003 H2 this past week, put in new knock sensors and harness, new gaskets, close up an exhaust manifold leak (the easy way - although he'd beg to differ) and tune up.
Was sluggish and slow to accelerate before and now it gets up and goes.
It gets better gas mileage than it did stock, and it is so much fun to drive.
Would definitely recommend to anyone needing a tune for their vehicle.
What ever needs you may have, John will definitely help you out or steer you in the right direction with your tuning questions.
John is a skilled tuner and great communicator.
I had my Ford Crown Vic tuned here and couldn’t be happier with the results.
