[tim_r73703]

downloaded the trial on a friends 06 cummins and when it was finished put the stock tune back on the truck and the first time he went to drive it the speedo stopped working and the check engine light, the abs light and the brake light or on and the turn signals wont work and the truck has 2 codes which are P0500-speed sensor and U0121-unknown code. Any help you can give would be great

I'm sorry johan, the orginal back is what was put back into the truck. Sorry, that's what i should have listed in the first post

Not sure what could of happened there, best bet would probably to call our tech line and have them do a force original backup into the vehilce.
