    I think it was just #1 and #2 or just #2 that was misfiring. I can try and richen it up for him. He had a larger cam installed. I have JET, HPT and EFILive install on my work PC. If he still have the old VCM in it I can make some adjustments with JET.

    It has been 2 months since I looked at it and when he left to go back to the installer I was thinking about the Cam and Fuel thing

    Well any GM dealer with a Tech II scantool can do a crank relearn, but
    the Snap-On Modis scantool can do it as well, you are more likely to find
    the modis at a small local shop than than the Tech II.

    Edit: day late dollar short.

    I think about 4:30 to 5 would work out. That would give me about an hour to look at it and maybe even make a few adjustments if needed.

    I will PM you my #

    well heres the final post for this thread! After chasing and chasing and being lied too by my engine installer, we found the issue! When they replaced the distributor cap they didnt attach the rotor piece, it was just sitting in there spinning on its own, I have pictures of the damage done if anyone wants to see a truely wrecked dist cap, this has stopped the misfire (BIG SURPRISE!) and shes running like a top now! just working on the tune to bring out the horses now and loving it, Thanks for all your help guys!
