    Default Throttle position issue

    Good day,

    I'm having an issue with an E92 swap and a lack of throttle movement. This is a '14 Silverado V6, using the original ECM and the Silverado pedal. I've logged what I believe to be all of the important throttle PIDS, and I see that my ETCPP1 and ETCPP2 positions are reading 100% at full throttle, but the TPDES never goes higher than 40%. I've tried this test with the car running and with it shut off, and I get the same result. I also had a look at any throttle limiting stuff I could think of, but found nothing. Does anyone have any other thoughts on where to look next?
    I've attached both logs, running and not running.

    Well that was easy! After I posted I decided to see if it had something to do with me failing the MAF while playing with VVE, and sure enough, as soon as I re-enabled MAF the throttle started acting exactly as I thought it should. Is there an easy explanation for that? Obviously if someone decided to do a MAF-less tune then the limited throttle would not be desirable.
