Where are you making your ground connection then? A lot of times the issues with these when you're grabbign a signal from sensors on the engine is the ground differential if you're not using the same ground path as the sensor. Here is a little install guide I made a few months back to help people out. Big thing is getting all your grounds in the same place and pulling your power from the same place the ECU is getting it so your 12VDCs, 5VDCs and grounds are all uniform. If you do have the tach input on the cam sensor wire on C3-P2, maybe redo the rest and see if that helps. If not, you may have a cam sensor that's on it's way out. Good luck and BTW, you need more fuel up top as you should be running 11's with that much boost. I'm curious how much timing your engine was pulling at those AFRs.
