All tuning at Gwatney Performance Innovation is performed by one of our calibration experts. We have tuned literally thousands of LSx / LTx based cars that range from stock and basic bolt-on cars, to 1000+ rwhp turbo and supercharged builds. Having tuned many record-setting cars, we have the knowledge and experience to fine-tune your car into a smooth and powerful combination. We also perform hundreds of Remote and Mail Order tunes each year.
We specialize in late model GM Performance cars and trucks. All of our tunes are designed not only to make great power, but to deliver unsurpassed drivability. Whether you are looking to make the most power, get increased fuel economy, or just change the way your vehicle’s transmission shifts, we can handle all of your needs from completely stock vehicles to highly modified all-out race cars.
We tune with the best equipment available to deliver a OEM quality tune. We are equipped with lab quality wide band O2 sensors and full dataloging software. Data does not lie, that is why we use the very best in data acquisition.
The best
I have watched a lot of tunes on Dynos but Ben is still the King of Tunes in my book. As soon as I can I’m coming back for more updates. I have had two tuners look at my tune and said it was the best they have seen. When I had my headers installed later their tuner was immediately impressed lol.
Good
This would really be more like a 4.5. If your thinking about it you should do it. I have a 2015 gmc Denali crew cab 1500 with 35,s. Made an awesome difference. Smoother shift points. Easier highway driving. And got rid of that darn v4 mode that gave it such a lag.
Ryan tuned my 16 SS Camaro, just bolt ons and it made 492 rwhp, 489 rwtq Car was so nice and E-85 added mega power as well! I miss that car something fierce! Now in a 19 Stang with good power, yet second to that Camaro!
