Power programmer Apr 27, 2011
By RP
"REDFORME"
Wow, this really woke my Duramax up! This was recommended by my Chevy dealer as the programmer that won't cause any real damage to my motor. Don't know if his claims are true, so don't take it to the bank. But this adds incredible power to an already powerful moter.
