On my turbo gsr 98. I keep having problems with my map sensor and it fouling out and then my car running bad. If I get a 3 bar map sensor, will I need a new ecu as well? I heard that bigger map sensors run at a lower voltage so you must have a map program written on a new ecu. If so where can I get a 3 bar and what kind of ecu should I get as well? All I have right now for tuning is a apex AFC which just doesn't cut with all I have modded.
