I have diablo predator since a couple of day. Today after a burnout a put the car in my garage. The tune was 93 octane. After four hour i take the car to go restaurant and the transmission dont chift. Its like is on the 3 gear. The tap shift dont worked too. After that i put the original backup and its ok. But what happen...i really thought i call the towing... ty for your reply

 

i think that you should contact diablo and ask them if theyve had problems like this with other challengers. the challenger 500 is a canada-only trimline, and while i doubt that it makes a difference, you never know...but if it wouldnt shift with the tune, and it shifted when you removed the tune, i think that it must have soemthing to do with the tuner.

i probably woudlnt mentioned that you were doing a burnout a while before it happened.
