Just got bike back from the mech and he's tuned it with the aftermarket TRE still on while i have flashed the ECU with the retards flashed. What will this do reguarding the flashed ECU?? Can i just take the TRE out or will it affect the tune of engine. I told mech to take it out but he's forgotten. Im about to take it to phillip island and want the gear position on dash functioning. Has a PCV.
