I have a 1998 WS6 LS1 that was rebuilt with a Bigger cam Comp Cam 224 228 114.0 581.581 valve lift and LS6 heads along with a TCI converter.I sent my computer to fastchips to be tunned to my specs but the car is not running right when I start it up the idle goes back and fourth from 800-1500rpm and then after it warms up it stayes around 1300rpm They set my rpm to idle at 600rpm which I know is way too low for this cam do you know what I should have it set to and if there could be another problem with my computer or engine that would make it run like this or do you thing think this could be a too big cam for my car.

Let me know if anybody knows a good mechanic around the LA area that might be able to help me out Iv'e had this car for over a year and want to finish it up and enjoy it.Thanks

 

Mail order tunes suck for well modified cars. Looks like you're going to have to find a tuner with a dyno to get it done right. Sorry, can't help you with a location.

 

Yeah, what he said. Ask on the western forums and see who people are using. Best of luck to you!
