That is what I was wondering. If you are running a 3.4", I bet my neighbor with a bone stock GTP would beat ya. Likewise...put a stock pulley back on that thing. Your car will thank you. 3.4" pulley most of the time requires something like @ LEAST, intake, 180* T-Stat, DP/U-Bend Delete/Headers, Tuned PCM, Colder Plugs.
So yeah everyone knows that you have KR. I had KR with a 3.5" and I had PEM's, 180* T-Stat, ZZP PCM, FWI, Autolite104's, 1.84RR, 3" DP, 3" Catback, TB Spacer, and other pointless bolt-ons...every car is different, but unless you compensate for the pulley drop your car will go boom...end of story.
