During dyno my FPR gauge showed me at 38 idle and when boost hits the needle jumps irractically and results showed A/F 15-16 Lean! and my enigine would not idle steady, my tuner says i need a new pump, new pump installed and now it idles at 40 still car doesn't idle normal, havent took it back to the dyno yet, but just wanted to knoe if i should get a FPR like AEM ..

Current setup is the Greddy kit 99-00si and new 310cc injectors
At idle what reading should you be getting on boosted engines? i read that its 10lbs per 1psi of boost if i'm only running 4psi should i add that to the 40at idle and get 80 on my fuel pressure gauge?

 

jump to see if you shot of codes that would be a good start. Then take it to a real professional and get it tuned . Thats all that I can say

 

I have no cel's, i thought that if anything i should be running rich due to the "blue box" but ill jump it just to see...
