Just finished modding my car for stage 1 minus the remap and im having problems with the car when its run on .85 bar on the gizzmo boost controller. The car seems to develop a missfire at high revs and dont have a clue why its doing it. Changed the plugs to ngk 7 iridiums hoping that would cure it but nope. Was wondering if it was hitting the fuel cut on the ecu but its just a guess... Any one else had this problem or has ny 1 got ny ideas? help would be great. cheers........
