RE: Ram 750f ecu's?
Sounds like some weird thingy happened to Jeremy's ECU and it forgot it's max CP set-point. If it happened to Jeremy, it could happen again. RPMTech, try it first. Reset all (set max CP back to 1300, if yours has a later model, settable ECU, and re-do the throttle calibration) and try it again. Be certain your batteries have a good charge and see if that does anything!
