Jhandy Posted August 20, 2015 Share Posted August 20, 2015 hey guys ok so having a few problems with the car, fully forged ep82 so went for mapping, turbo was to big blah blah blah went back for mapping on a td05 16g, now it builds boost fine, and gets there fine, but the car will only revto 6500 also with a little misfire, now i have another coil to try, and also some msd ignition stuff that im gonna put there anyway. but what i can work out is if i do a half throttle pull, it will rev higher than 6500. and it has only made 230bhp on a emu. now surely i should be anywhere or above of 300bhp plus. if anyone has any ideas what this can be, would be great, i have checked timingwhen the cams open and closei have even had a engine builder check the cams timing etc im pulling my hair out, and mapping is starting to hurt my pocket jake Quote Link to post Share on other sites

AdamB Posted August 21, 2015 Share Posted August 21, 2015 Throttle position sensor possibly. First check would be to make sure it's calibrated correctly. Quote Link to post Share on other sites

Jhandy Posted August 23, 2015 Author Share Posted August 23, 2015 Pretty sure it was a knackered coil. As it was all broken down. Quote Link to post Share on other sites
