recently my car hesitates in boost. at just about 1 psi my car bogs and hesitates. i cant figure the problem out. my a/f shoots lean but then returns to 13.5:1 and the car runs fine until boost. i thought it would be my boost controller so i disconnected it and the problem is still there. No CEL. any help or suggestions would be great. thanks!

 

oh at 1psi?..........

hm, how about you NOT boost then. What engine management are you using?...........hopefully you didn't just slap on a turbo without getting it tuned.

 

well i ment at the sightof boost it start to bog. i had it street tuned with a wide band and a v-afc. i just ordered an aem ems but the thing that bothers me is it was running fine until last week.
