I finally got the car to start with the chip, but the car is running rough. It spudders and black smoke comes out the tail pipes. I thought I had a bad MAF sensor, but nope I bought a new one and still same problem. I adjusted fuel pressure, still same problem. With the fuel pump, you can hear it pressurize, but the sound doesn't stop like normal when you turn the key. When I pull the chip everything runs fine. I would call the place that did my custom chip but they work the same hours as I do.
