    2010 Yukon Throttle Problem!!! Need Some Help.

    On the tune i did for this truck there seems to be a problem that i cant seem to find. When you lightly press the throttle from a stop the trucks RPMs goes nuts and the pedal doesn't do anything then the truck dies, it restarts fine and if you get in it hard it stumbles but then clears up. any help would be greatly appreciated. (the truck is stock)

    Why are commanding such a low idle speed?? 475 is far too low.

    The min idle speed VS the vss is higher, that could be a factor.

    Other than that I just see ton of torque mngt stuff taken out, most of which I'd never touch on a stock vehicle.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.

    The idle speed is reduced for better fuel economy when in traffic or just running in park. That was taken from the tuning school advance guide. where would i find that table you pointed out? Would there be any problems caused by the DoD being enabled?
