Today my LGT was in for a clutch replacement at AZP. I figured while it was there I would have a compression test done. The car has 120k miles on it and has been Stage 2+ tuned for over 70k miles. I'm very happy to say that my results show what a good pro tune (thanks EFI) and proper maintenance (thank you AZP) can do for you. The front cylinders are at 155 and the rear are 150 Although Mike says it pretty rare to see motors that strong, I'm glad it's mine.
