    He's around, and working for Cadillac in NC. I believe that he's doing an engine for a member right now. Look for his work on early ECM's in the "PCM Tuning" thread............... his login is "pcmcalibrators"

    Sub, I knew the history, remember I'm one of the beta testers. I've had several AJ Tunes in my 01 but after he moved he stopped communicating.

    The two Northstars I've worked on had evidences of leak on #1 cylinder. All bolts clean and no threads coming out either.

    The last two had pulled the threads out of the block, I think the twisting on the aluminum block is the most problem for torque problems

    I wonder what it is with the #1 cylinder. Maybe it heats quicker?
