Hey there, ive been working on a map for a friends car for quite a while now, and i think ive been looking at it way to long because i cant see problems anymore, yet things arent running right.

I got all the port air and smog pump stuff working ok (smog pump clutch doesnt turn off actually), but all the valves and solenoids work fine.

With a streetport, DP, High flow cat, 99 turbos, intake, intercooler etc....i get 14 psi by 4000 rpm without much trouble, but there is no power! Any suggestions? My afr's seem ok, logging at 10.5's in the 14psi area on the dataloggit.

I basically smoothed out and corrected the PFC map that came with it, and got rid of any trouble spots (like negative split), but the power just isnt there for some reason. Motor is fine and compression is fine and turbos only have about 5k on them.

Any suggestions of what i should look for? Should i try and get my map from him and post it or something? Sigh, so frustrating sometimes...

 

10.5 AFRS at 14psi boost is way over rich. Tune it for 11.2 to 11. If you need it this rich to reduce knock, then you have too much timing advance.

Post the P row timing that is uses for 14PSI.
