Okay so I thought I had the 3800 hestitation fixed after I regrounded the ECU everything was fine the car was running great no hesitation . I had even regrounded everything under the hood . Checked the TPS works perfectly . Boost sensor works . I dont know anymore the car was running great for a day then the next its back to running the 3800 hesitation again . I made a vid check it out tell me what you think it is . Watch as the Tac climbs normally then it hits 3800 and starts bogging and climbs slow .

 

I figured out what it was I had made one of those homade ORFACE'S and the appoxy on the inside melted shut after it was on the car for a few days causing my boost sensor to not sense anything lol .

 

Your oraface sealed shut? Ouch... sorry to hear that.

Glad you figured it out though.

 

I redid the orface and now if I work up the rpms slowly it will be okay but if I step on it . The car starts jolting in and out of bog ?
