Tried several times to load tune with ecm in the truck...It takes about 20 minutes just to do a back up flash...swapped ecms with an 06 same issues...pulled ses fuse no help ...anyway wont take a tune unless its on a bench... After a wide search seems to be mostly 03 trucks...have plenty of battery power and laptop plugged in.its a engine swap from 03-4.8 to 06-6.0 with all the goodies ...any user advice /changes to get it done inside the vehicle? man we are lost?

 

happen to have an aftermarket stereo in the truck?
