[faisalQTR]

Hi guys i just bought Trinity diablo for my truck Gmc 2006 4wd 5.3 L and i install the diablo tune in it but i didnt feel any different and i tried to do the speed limiter like for 60 mile to make sure if that working but no response !!
and i have the 87 octen option , diablo tune and hp factory tune is that all

am having 97 octen in my truck should i update the trinty be4 installing it to my truck

and where can i get high performance tune for my truck any idea



thanks guy

your 97 octane is similar to our 93 octane, so the diablo tune is perfect.

and yes, those are the only tune options available for trucks... 87 octane, Diablo Tune which is for 91/93 octane, and the factory hp tune which is just a copy of your original backup stock tune that lets you make changes to the stock tune if you don't want to use either of the other two performance tunes..
