well mdrush, i dont know what to tell you, except, im having the same exact problem, scanner is telling me -20 degrees cam timeing, i go one tooth foward, and come out with +35 degrees cam timeing, ive got a few hours into mine, incluiding a new delco distributor, 10 attempts to reprogram the cam/crank sencer to no avail.., set the vcu to base and it blinks the 1345 at first 1k rpm signal reached, im running out of choices and options here, but if it will help you any, i fudged up when i had my vcu originally programmed for the v 8 and had the v 6 distributor and reluctor in the truck, that gave me a timing or 24 degrees retarted camshaft timeing...
