Hey guys. I thought I hit the lottery because my buddy gave me all of the parts he took off of his lightning. The parts have sat for a few years but he gave me a 6lb pulley and a chip tuned for it. I installed the pulley and the truck still ran. I installed the chip and now it wont idle. It runs if you keep it around 1000rpm but it smokes up my garage and seems to be EXTREMELY rich. So much so that fuel is coming out of the exhaust. We have removed the ECM several times(with the batt diconnected) and checked the contacts but it still wont run. I dont know where to go from here and may have to remove everything and leave it alone. The only thing that scares me is that we put the ECM back in without the chip and it wouldn't even start. I am out of time and will have to resume tomorrow after work. Any ideas? Thanks.
