I replaced the plugs with the ones coz sent me a while ago. I'm pretty sure i re-gapped them to the right spec but it has been so long. What reason would the car only start to misbehave when it is hot out. If it is cold it will boost fine. I also did a ptu relocate and it has the newer style ptu. I don't think that it is an issue with the car running to rich at all. It definitely seems like an ignition problem though. I'm just having trouble with where to head. Like i said its only under a high load. As for boost levels i don't have an aftermarket gauge in the car but i have .045 jets installed at the moment. So im guessing right around 12psi?
