thanks chris. I have to get to bed now but if you are on tomorrow night i will post more about it. I haven't really done all that much to it other then slp headers and catback, i had a tuned pcm with just the basics, also the k&n cai under the hood. I bought a smaller pully but i was waiting to get a xp cam or soemthing at the time and thermostat and colder spark plugs before i put the smaller pully on. Now i am thinking because I have 2 other cars i use for everyday driving. i would just go crazy on my grand prix and just make it a fun car, at first i was thinking thrasher engine and thrasher cam... i have another transmission i was going to try and rebuild on my own just to learn.
