I need help really bad. I have a 92 si hatch with an h22/turbo. My problem consists of ......when i drive and it starts boosting up ....around 5000rpm or some....it starts to bog and jerk...until i change gears and so on so forth same deal. So i took the intake piping off to see if does it when i have N/A....well when i hit bout 5500(give or take).....same stuff.....drives normally until i hit that rpm and it starts to break up...or so.....kinda like a stutter box or so. I have no check engine lights on....had knock sensor but some what took car or that.

My set up-----H22a, turbonetics t03/04. waistgate, msd ign, blaster coil, stock head, stock injectors, holley FP, vortech fmu, aeromotive FPG, p13 ecu with missing link on map sensor, 3 bar map.

Any help would greatly be appreciated because this mess is certainly getting on my last nerves.

Thank you

Pat
