throttle body is holding you back a little bit, even when i designed the stage 2 cam way back in winter 2004, I designed it for a 65mm tb, with the 65 flowing around 10% more than the 62. When we dyno cars over at Dynotune Motorsports in Columbus, the stage 2 cars almost always make the same numbers. a 65mm tb'd stage 2 package car will make 195-200+ whp with stock exhaust manifolds. headers usually add around 10-15whp or so, depending what they are. 187 with headers sounds low. Have you done a compression test? what plugs are you running? gap? what pcm?

as for the slip, I was looking for numbers like 1/8ET and mph, 60ft time, etc.

not sure where you're located, but if you wanted to bring your car into the shop, I'm sure we could find the problem and have your car running a whole lot better.
