hey guys i am running a manual boost controller and lately i have noticed some major boost creep. the only thing is it only happens when i am in a lower gear and i allow the turbo to spool. if i am at 2000 rpm in second gear and i give it gas when the turbo starts to spool it will jump from 3000rpm to 5000rpm for about 2 or 3 seconds then it will settle back down to 3000 rpm and go normal from there. the funny thing is if i am at 4000 rpm in second gear and the turbo is already spooled and i hit the gas the car pulls great. i dont know if i have a vacuum leak or what, any thoughts...?
