I am going to go to the track tomorrow to see what I will run. I had a 2.9" pulley on the car and ran a 14.8 which blew. I could not figure out what was the matter until I heard the belt squeaking...apprantly when the pulley was put on the tensioner was broken. I took it to the dealership and they replaced the tensioner and I decided to put the stage 2 pulley back on. Right now I have stage 2, GMPP catback, CA downpipe, and GMPP honed manifold...hoping since the belt is not slipping now I will get low 14's at least. Keep in mind this is a high eleveation track. Also, I lack the driver mod, could anybody give me some quick tips/
