I am so frustrated with my car at the moment. Despite the misfiring problems I've been having, I now have a new issue... surge.
I am putting a video of this up shortly, but in a brief description, it sounds like my blow off valve is actuating partially during acceleration. I thought these were electronically controlled?
Also, during slower acceleration, the car builds boost and dumps it, builds it, then dumps it creating a surgey slow acceleration.
I think tonight I'm going to pull the battery and do a ECU reset... I may even reflash my car... Can't I have a tune that works as is?
