Background
I started my journey with DSM's in summer of 2000 after purchasing a 99 GS Anniversary Edition off the lot. I turbo-charged that car in short order and drove it for roughly 5 years until I decided to make the jump to the 4G63 platform. I was searching for an X13 GSX, but came up short and settled on an X13 GST. The car is currently is setup with a mild street build. Future plans involve swapping the car to the GSX I always wanted and then running more power through it via a larger turbo and more robust fuel / engine management system.

94 Octane Pump gas. Photo link is of the only dyno sheet I can find right now. We made a few minor fuel and boost adjustments after the sheet linked and the car made just north of 300. Video link is of an older dyno session several years before when the car had less modifications.
