Well I raced my friends 99 trans-am WS6 auto. Its the one with the blue iodized rims, ram air, I think its like a 25th anniversary edition. Anyways I think he's got just an intake but we raced from a 1st gear roll.......... 1st side by side, 2nd still side by side, as soon as I hit 3rd he started walking me pretty good. I would say up to 100mph he probably had me by 2-3 cars. I have I/H/E. I never knew those cars were that quick. Or maybe mines just a sled.

 

Iused to have a 99'.. yeah i'm suprised he didn't pull any harder aka bus lengths!!

 

He should have beat you by about 8 to 10 cars, maybe more. Those LS1s are solid 13.3-13.6 second rides. Your modded TL is probably a lower 15-second car.

 

T/A needs a driver mod!
