I've got a 04 C5 that had a predator tuner in it.I was changing fan temps and reloading the changes.The tune aborted,set a code,that said no comunicatio to the TB.The car won't start.I was gonna tune with HPTuners anyway.I tried to read the tune and My HPtuners says,can't find computor,is key on,Failed.Predator says when it aborted the tune it blanked out any info in the pcm.They said take the car to Chevy and have it reflashed.Can I somehow put a stock tune back in the car with HpTuners?They said that there 6 yr old hand held is junk and needs to be upgraded.WTF Thanx for the help.
