So I when and install the 65hp program and that seemed OK I drove around and returned home, went to reinstall the original back-up and No go and the truck won't start?:confused:

Welcome, fill in your signture helps alot, and starting a thread in the Third Generation electronics you will get alot more responses there. Did you have your truck ECM reprogrammed at your dealer? If so you'll need to update your Diablo preditor. http://www.dieselplace.com/forum/showthread.php?t=264377&highlight=Predator+major+issue%2Fhelp and http://www.dieselplace.com/forum/showthread.php?t=243394&highlight=predator+reved

Did you call Diablo tech support?

Thanks for your help I'll have to wait till monday to contact Diablo

you froze up the ecm did you read the instructions usually on programmers if you do not pull specified fuses it will cause this problem and then you have to have your pcm reprogrammed and a new programmer installed, you gotta love all these performance mods they say are user friendly

that throttle issue has happened to a few people. Usually downloading the latest update for your programer will fix that issue
