U7192 9R11. 2006 SILVERADO 5.3L. EVERYTIME I TRY TO ISTALL A DIABLO TUNE IT SAYS WAS NOT COMPLETED UNKNOWN ERROR. ANYBODY KNOW WHATS GOING ON AND HOW TO FIX IT?

Got any aftermarket electronics installed?

Does it restore the stock tune?

WHEN I FIRTST BOUGHT THE TRUCK IT HAD AN ALPINE DECK. I BOUGHT THE TUNER PROGRAMMED IT DROVE IT FOR A MONTH WITH NO PROBLEMS THEN I PUT A NEW DECK IN WITH THE MODULE FOR THE BOSE SYSTEM TO GET RID OF THE ALTENATOR NOISE. EVER SINCE THEN IT DOES THAT ERROR THING. I UNPLUGGED THE DECK AND STILL DOES IT.

Unplug all the wiring from the factory harness.
