I don't know about all of his work, but a friend of mine had his car tuned there and he is far from happy with it. It's a cam only (224/.581) '99 and he got it back with surging issues in the lower rpms when the converter locked and he was told something about them having a difficult time getting enough fuel to the motor for it to be tuned right. Granted, this is all hear-say coming from me and I don't know the first thing about the quality of work he put out on a regular basis. But, for the price of the tune and what was delivered...I would be somewhat disappointed too.

 

I had similar problems as well. I had to take it back a few times. I especially liked after the first dyno I was told my SS was putting out 290 rwhp with all my mods. Anyway, the reason I took it back yesterday was for the same surging issue your friend had between 35-40 mph.

 

I thought greg was a great guy, when he had dsw
he worked on a few different cars, no problems
and i still think greg is a great guy.......................................
