Had a fellow rider show me the tune routine last week, and didnt realise the Nixon map was fine to go on without the tps light turning green, so went instead with the arrow low level system, which doesnt run well. Definitely not as well as stock cans with stock map (thankfully still have). Yet I didnt realise this tune is for a full arrow system, with very different headers, will get the nixon map on when my cable comes next week and hope it improves.
