after installing a perfomance chip what steps need to be taking into account
i instaled a perfomance chip today and the car wouldnt start before removing the stock chip i had a check engine light which needs to be reset and after installing the perfomance chip the check engine light was off. tried to start the car but it wouldnt, i filled it up before installlation with 93 octane. when i put back the stock chip it starts with no hesitation. could the chip be defective or i am not doing something right.
