Ok i have a 88 t2 with a large streetport three inch intake down pipe to two and ahalf pre silencer, fcd, just got my secondaries back from rc eng and they are much better than they where but im still haveing the prob with my car hiting like a rev limiter at 3800 while just free reving then i loze complet power anywhere from 3800 to 5000 while driving when i start to really boost and when the peddle is down is when it happens and it sounds like its not even running then i let off of the peddle its sounds like it starts right back up im so freakin confused have thrown so much money at it and im tired have checked the codes the only one it shows me is the pressure sensor and i have just put the restrictor pill in it and it still does it and the pressure sensor is pretty new any ideas would help thanks guys

 

TEST the pressure sensor, make sure the connector and associated wiring is good ALL THE WAY BACK TO THE ECU.

 

Ok how do i go about that and whats the specs on everything being checked.
