Where are your fuel trims at and the corresponding RPMS?
Try and get them as close to 0 as you can. +/-3 is perfectly fine. After logging and tuning a couple of Evo's I might change it to +/-5 which is OK too.
It took mine car a full three days (maybe four) for LTFT's to settle at 0% at 3000 RPMS. I'm +/-3 everywere else.
You just don't want things so far out of wack that the ECU can't do it's job
