4doorboost
Well-known member
so out of nowhere my car started missing at upper rpm. at first it was around 4500 so i backed down the boost and now its up around 5500-6k. i get no check engine lights. tps sensor is reading fine. im gunna change the plugs today and see if that helps. maybe my tune is off, but it never used to do this. i could run 20psi no problem and now i have the boost at 16 and still i get upper rpm misses.. could it be electrical or possibly fuel
any help appreciated. thanks
