Has anyone used this tuning shop? I never heard of them in the past couple of years, but recently it seems a lot of people use them in my area. I was seeing if anyone has feedback for their G8. The owner said he has done about 5 G8 Gt's and most of them are running 12.8 with just a tune and nothing else. I am going to give it a shot and have him tune my car tomorrow. I have been running Superchips roto fab 93 for years, so I figured I'm ready for a change.
