Ok, Heres what I got. I have a 94 camaro I just did a cam install on. specs are .528 intake .535 exhaust on a 112 lobe seperation and the cam is advanced 4 degrees. I also did the 95 Opti change. Now I have a 95 Trans am with a hotcam install done and I had it Dyno tuned. So I took that program and installed it on the camaro. Needless to say, the car runs horrible at idle. I do not have any mechanical problems ( vacuum leaks , rockers adjusted correctly, all that good stuff) I took a look at the timing tables and noticed that the Dyno timing is actually less at idle than the factory timing. Am I missing something here? I have always had to add a little timing to a motor with a cam compared to a stock cammed motor. The T/A runs great. I know its a different cam but I would have thought it would of idled better then the stock programming. Any ideas. I am stumped. I do know that the Left Bank is running lean and did trip the ses light. I also am running open headers on this thing.
