Interesting response Tuna...
Do you run a Motec? a close friend of mine 'UNDRGND' (04 STI) ran an M8800 but could never get it to run right, bad idle, rough boost etc. Obviously tuning issues but even when he had it retuned it still was 'not quite right'. What Motec are you running Tuna? "UNDRGND" ended up ditching the Motec and returned to the standard
ECU and recorded 250kW atw. Personally I would rather reflash the standard
ECU but thanks for the ideas.
