My 1998 GTP is slightly modded it has a thrasher CAI, with the 3.4 S/C pulley+ PCM, A Custom Straight back exhaust i made my self (sound wicked), a 180 t-stat new plugs and wires,and new wheels and tires all around 265/35 on 16" polished aluminum.Now my friend has a 1999 camaro z28 with a ls1 stock except new wheels and tires but there only 240/40 on 16" (not quite as wide as mine), polished aluminum, and new dual exhaust except no headers, Iam not sure how much power iam making out of my GTP but it's crazy compaired to it when it was stock, My guess is around 300whp and 355flbtq to the wheel. Who would win?
