I tried to load the 93 tune into my dsp and it tells me "original backup NOT SAVED (-30)" And "not tuning because of backup (4)" and then"predator is rejecting back up , it appears to be a predator tune". This is really confusing me and I really don't know what to do please help me

Sounds like you're vehicle has been tuned before. Please give us a call with the tool powered up for a force calibration update.
