I have a predator in a 04 lightning. I have a custom tune from predator technical support that is in the truck. This morning I went to put the stock tune back in the truck to unlock the predator from my lightning. I accidentally installed the custom tune back in the truck again because I could not find the performance tune to scroll thru to find the original back up. I went into options and erased the custom tune that way. Now when I go to performance tune I cannot find the original back up tune...it is not under the performance tune. Where would I find the original back up tune as I am trying to unmarry the predator to my lightning?? I know the stock tune is not in the truck because the power is still there. Please help!! tHANKS. If it is to technical to explain please call me at 727-432-7715.
