The car runs very well and the transmission tune is spot on. All of my performance goals and car manner requirements have been met. Pat was also patient with me while I figured out the email tuning process, which was new to me.I consider purchasing this service as money well spent. If you are on the fence about what to do just go ahead and get a professional tune here. You won’t regret it.

This is the 2nd time Pat has tuned my CTS-V. 1st time after pulley change, ported s/c, headers, injector change, and bigger heat exchanger. Six years later, I added a cam, CNC ported heads, and a bigger lower pulley. Patrick dialed both tunes in remotely and the car runs and drives great. Got back to me very quickly after I sent him logs and with his experience, it didn’t take long for him to dial the tune in. Highly recommended, very professional.

Pat hits it outta the park again on a retune after a few modifications are made. Pat makes its simple and easy while explaining the process. End result is factory like manners on a modified setup. Doesn’t get any better. HUGE thanks!

I’ve been using Pat to email tune my C6 from day one. He’s a pleasure to work with and his tunes are always spot on. I will continue to use him in the future and would recommend him to anyone looking for a tune!

Pat G Tunning is the best. I have not dealt with anyone that comes close to Patrick when it comes to Email tunes he pretty much nails it by the first data log is sent to him. He has tuned my LSX454 2010 Camaro which was a N/A car. And he just finished up my 2018 c7 G/S that is forged cammed and supercharged with E85 and the car is a beast! You will get the best tune for your money from Pat G don’t waste your money or time looking for a tuner he is the man! I only wish I was closer to Texas to have him dyno tune it. But I don’t know if it could be any better than his Email tunes te tell you the truth. Thanks again Pat you knocked it out of the park again I couldn’t be happier great job!! Take care.
