    Why is the idle timing so high?

    Shouldn't require 30+ degrees of timing to idle. Somewhere around 20ish is likely better.

    You didn't put the rest of the injector data in either, so that is all...

    You could flash the TCM with a GM tool with the operating system for your VIN so that both the PCM and TCM match again.

    I've never tried it but I don't know if HP Tuner would let you write entire...

    Just the reset/preset, I never click fast learn on anything.

    You'll know if the thing worked when you put it in drive and start moving, the first couple shifts are kinda clunky as it relearns.

    Rusz, you engine isn't 25% larger so you don't need 25% more fuel. It's going to be really rich just so you know.


    To the OP, you need larger injectors, the stock 25lb/hr won't support a 6.0 with...

    You are getting the data if you are logging it in the channels list on the left.

    Did you do a compression and leak down test on cylinder 7 yet?

    I don't see the tune being the problem, that is a very tame setup for wide open throttle fueling and overall timing curve.

    The thing in the charts will only work if the "Knock Retard" channel is present in the channels list. The channels you have listed aren't that specific channel so it won't report any data there.

    Doesn't matter. That drop down menu does nothing anyway. The cylinder volume is the only thing that matters.

    I wouldn't but that's just me unless you can flash every one you got with a GM tool to a 2001 Tahoe VIN/OS.

    I'd just do the single VCM license.

    2 credits for just that VIN/vehicle.

    Post your file.

    Or open your file and look at the calibrations details page and then controllers. If the FSCM is listed there, remove it and try the flash again.

    David you are right about the DoD camshaft. You can't put non AFM lifters on those lobes, it will always misfire.

    Does it smoke if you take the charge pipe off the turbo and run it NA?

    If it does then I'd guess at valve seals or piston rings if it's a aluminum engine. I thought the LC9's had that issue.

    Are you pressuring the crank case?

    Does the turbo require a oil restrictor so it's not blowing past the seal and eating the engine oil?
