bully dog tuner
 

i have the dreaded late model 04 f250 6.0.. i have been having problem after problem after problem. i had the bd triple dog power pup downloaded when i decided to remove it and see if it would run any better or for that matter any worse. while removing this tuner,, the screen went blank,,,,keep in mind it says do not stop or turn off key,or whatever it said,,,,anyway the backlight stayed on but no words.. so now when i try to start it, i turn the key,,check lights come on then go off, like normal,then try to crank it and nothing, not a click from starter not nothing... did this downloader fry my ECM or can anyone tell me how to fix this ?? HELP PLEASE
