Ok, when I'm in low boost(6psi) my car drives fine, no problems. But when I go to high boost(10psi) it feels like its missing from around 5k-6k. My a/f gauge is also pegged on rich all the time, I dont know if the gauge is screwed up or if I really am running that rich. The odd thing is, the car was perfectly fine at 10psi for the past few weeks. I started having this problem just recently after I got the new clutch in. The rpm's just dont want to climb in high boost, its especially bad in 3rd gear. Has anyone else had this problem or know how to possible fix it? thanks

 

Yeah I was having the same prob except that I don't have boost. I was a weak coil and a plug wire that was loose. Threw my MSD 6A and Blaster 3 on there and it was all better. If you have a knock sensor you comp could be sensing detnation and retarding the timing a lot, which would hurt performance. Mike

 

problem after putting clutch in?

maybe check ALL your grounds...

i hope it is that simple

Spark plugs?? Just guessing cause on the Saab BB everybody that raises their boost says the plugs get more important. With high boost the car does NOT tolerate the plug gaps opening or a little fouling that would be OK with normal boost.
