Ya id start over from the beginning...if you put the stock air filter back on are you getting codes? If not id start over with the neg terminal off and give it another shot before returning it. I've been in for warranty work half a dozen times or more and return to stock form from cai and ported throttle body every time. Where im at... if you tune it they cant wait to deny warranty work.
