    My understanding is it’s a 12.7 Ddec IV in an 07 Freightliner. Maybe a glider? No telling what parts are inside the 12.7 or if the ecm, is set up accordingly. That’s the problem with the rush to build gliders it seems. Like a box of chocolates.

    What was the problem?
    My guess is boost sensor or barometric pressure sensor.
