    Thanks snowwy - I didn't think about that. I've come across it here in MO too, with a 4 wheeler.

    Yes - the kid doing the dyno said they look for 80%.
    They managed to communicate with the ECM, but as said, no data.

    What is the EGT? - You mean Engine, Gearbox, Trans? 12.7, 13 spd, 3.58.

    Lightbulb just went off - EGT was not listed on the dyno report. I didn't think to check it during the test either.

    You can't test it unless you add a port before or after the turbo

    Where was the dyno work done at?
    I put down 465-470 every time this goes on the dyno, and it's a S60 515. Same dyno, which is the only way you are going to tell a difference. This put down 440 one time, and they found a bad camshaft lobe. After the cam it went back to 465-470.
    If the driveline is tight, 80% or better is what they should be aiming for, so yours should be at least 400hp, from experience.
