I know this thread is a few months old, but did you guys get your problems fixed by guilt-toy??? I am in the same boat here, engine does not have any problems on the dyno, but on the street its not very friendly with my engine light flashing from 6000rpm onwards. Car just been "re-tuned to clean it up" as they said, still SAME THING happening. Bummer.
keen to get this problem fixed soon!!! Any tips or help would be greatly appreciated, thanks
