    need some advice

    I have a diablosport trinity tuner I completely removed the tune using the diablosport to unmarry the device. Then I tried to use Hp Tuners but said failed to read. Could this be because of the previous tune. Do I need to have my PCM flashed by a Tech 2? Thank you! 2006 Silverado 5.3 flex ccsb

    did it identify the truck/pcm on the read popup? you may try reinstalling hptuners vcm suite. Have you tried using the scanner to see if it reads?
