I've only owned my evo for a couple days and I was doing some research about the knocking/fouling out issue that 03 owners have experienced and I didn't see if anyone has tried installing one of the ignition system amplifiers to solve the problem. I know the car has an upgraded turbo kit on it, and it has a forge bov and an apexi short ram, and I think those may be causing the problem, but it has the factory spark plug cables with ngk iridiums and such on there. I'm getting the car checked out by a local tuner in Virginia Beach but I wanted to know if anyone has any other suggestions. The only management system I know of on the car is the apexi safc controller

Thanks,
Seth
