I just got my trinity T2 and hooked it up and I was wondering what the best tune is for my 5.3????
I have K&N intake and cat back exhaust installed as well
Best tune for GMC Sierra
Re: Best tune for GMC Sierra
if you use 87/89 octane gas, then select/install the 87 octane tune...
if you use 91/93 octane gas, then select/install the Diablo Tune...
if you have a 2007 or newer sierra, then select the Firm Shift tune for the tranny tune....

Re: Best tune for GMC Sierra
I have a 2016 and I’m using the Diablo tune with the firm shift. It’s great but I keep getting warning messages for “IAT”. What is this???
Re: Best tune for GMC Sierra
IAT is Intake Air Temp... . not a tune issue... that's an issue/problem with your truck... use the tool to scan for trouble codes.. have any trouble codes? could be a problem with your MAF sensor...
