Finally got her Dyno tuned Made 644/613 and got rid of that pesky low rpm slight pinging (I had to make the car ping but the fact that I could bugged me)..Greg is great and the shop is great and the TUNE is great.. drives like a different (better) car now has more manners and of course more POWER...I couldn't be happier with my mod choice and tuner choice. I love that Greg is a perfectionist and seems to really have a "feel" for these cars.
