I'm working on getting the facebook video embedded on here...until then...
Ran a '98 LS1 Camaro, A4. Had some suspension work, a gear (3.73 I think he said), intake, exhaust.
Anyways, case in point...I was in the GXP, Built trans with 3.69's, hai, 3" DP, exhaust, tune, poly mount.
Dig wasnt too pretty. By 110-120 he had 2~ cars and creeping farther.
20 roll was much better for me. Hung dead even until about 90~ when he started inching. Had half a car by 110~ when we shut it down.
Overall, I was impressed with the tank. I thought it was going to be so much worse. Can't wait to get the bottle hooked up, my new front mount, and get it re-tuned...maybe with some traction I can go back out and reclaim a few W's.
