had some problems with the stock map recently and just switched over to a 3bar, +40's, and a stage 4 FWD cal. Car ran great before with the stock map, just had to be unplugged to idle smooth. Anyways, just installed everything today and car runs on 1, maybe 2 cylinders. Everything looks good on the scan tool other than a code 53. Is this a problem with the new ecu, or should I look elsewhere on the car?
