How fast does your exhaust and bumper around it get black?
Just wondering if everyone else's bumper and exhaust get black quick. not sure, but that may be due to the fact that the car runs so rich at the top end. my old car would do it when i was running rich.
Sorry, lame I know. But I wanted to get it in before anyone else did.

To provide something close to useful, I'm quite sure your problem is the rich mixture up top. On the DSM ECUs, Mitsu ran the A/F mixture around 9.5:1 above 6000 RPM. I'm sure the same is being done with the EVO.
Either lean it out or get a really long exhaust tip I suppose.
