    supercharger will not work while on cruise control, whats up with that

    Its an 07 HD with saleen pkg. If I'm going down the interstate say 70 mph and start up a steep hill the motor will not utilize the supercharger and the speed will drop down to say 60 mph and then the cruise control just turns off, not enough power to go up hill without SC. Then I give it some foot and the SC works like normal as long as I don't use the cruise control. Its a pain. What would cause this? Basically every time I go up a hill I have to turn the cruise control off.

    Sounds like your trucks computer when on cruise will not downshift and just holds itself in OD instead of increasing the RPM's to compensate for the hill...curious if this is a programming thing done by Ford similar to the speed limiter that came with those trucks.

    That doesn't really sound like an s/c issue, it sounds like oki said it's not kicking down a gear. Seems like a cruise control issue not an s/c issue.
