I installed a 2.80 pulley and Superchip last night and now the car will not run properly. The car has stalled a few times and also violently jerks when trying to accelerate. I cleaned the contact with the green scrubber that is supplied with the chip. How much cleaning does it take and what color should the contacts be? Also the chip does not fit flush...there is about a 1/4in or more space between the chip and the side of the pcm. I would appreciate any advice I can get. Thanks
