Greg is the best tuner there is. Period. I have had no less than 5 blowers and turbos on my car in the last 4 years. Greg tuned them all. I have been beating the shit out of my car for 4 years on the same shortblock. Pump gas, meth, and e85. I'm pushing over 900 wheel on a 2v!!!! Let me say that again... GREG TUNED MY 2VALVE TO 903whp!!! 21# on a single streetable turbo!! I run street and HALF mile racing. TUNING DEBATE IS DONE. Greg is a great guy. I went to him because I had problems with a local tuner. I drove my car 90 minutes to him and he had the problem fixed in 30 minutes. My car won't be touched by another tuner. I'm getting the itch for more power and Greg will be the one doing it. It's a NO BRAINER. There is always two sides to a story. Greg has always responded to my calls and emails and I will continue to go to him and stand above the rest on the street
