Hey all, trying to mix our boom truck, freightliner m2 with a Cummins cm2250 and manual 6 speed. When I turn pto on, it revs up to 900 rpm instead of 1100. Trucks revs up fine with cruise control, but once pto switch is hit it only goes to 900. Anybody see this before? Thank you.
Also I tried going into parameters and nothing changed when I tried raising idle set speed for pto.
