    HELP! Reduce Power Mode

    Truck will start up and idle great. I take off diving, and everything is running fine until I get a couple miles down the road. It goes into reduce power mode, and I can see on the scanner that I am getting torque management from ETC and fuel trims. I let the truck sit for a few minutes after clearing the codes, and was able to drive it back to the house. As soon as I turned onto our street, the same thing happened. Same torque management as well.

    Codes generated:
    P0068 - MAP / MAF - Throttle Position Correlation (SES, Pending, Current, Permanent, History) (Both Logs)
    P0106 - Manifold Air Pressure (MAP) Barometric Pressure Sensor Electric Circuit Output Range and Performance Problem (First Log Only)

    Current tune and logs:
    SD Open Loop Step 03.hpt
    Limp Mode Log 1.hpl
    Limp Mode Log 2.hpl

    Didn't look at the tune, but going off of the title most likely because your tuning sd. Set the test parameters for those to not run then you should be good to continue.

    I will make those changes and see what it does! I really appreciate everyone's help on here.

    Question. Why would I need to make those changes on this truck, but I never changed those parameters on my other truck and it never gave me this issue? Will cam size affect the difference? Did I just get lucky on my other truck? Other truck in question is an 09 1500 5.3l and current is 09 2500 6.0l
