Default hypertech? vs CD head unit
I bought a used hypertech III tuner when I program my truck it will not tune unless i unplug my aftermarket cd deck. this has become very obnoxious. Has anyone else had this problem? and if so what is the cure? Also the 3 power levels are 50 70 and 90 if that helps any? THANKS

Ive heard of having to pull a fuse when uploading a programmer to some trucks but Ive never had that issue.
