So i have the trinity programmer for my truck now and like to know what is the most recommended program to run it in. I currently just have a cold air intake and a magnaflow exhaust dumped in front of the rear axle. Also how do i shutoff the active fuel management on the truck.

if you use 87/89 octane gas in the truck, then use the 87 octane tune... if you use 91 octane gas or higher in the truck, then use the Diablo Tune...

select the tune you want to install, then select Modify Tune... and you can disable the dod/afm in there and then install the tune...

So got the 6.0L with the hydromatic 6speed transmission anyone got a good tcm tune. Im currently running the 87octane tune on the trinity.

So when is Diablo gonna come out with TCM tunes for the chevy 6speed transmission? I know i was informed that i can send you my factory back up and you can tweak it a little but im wondering about like a set tcm tune that will auto update on my trinity. Thanks

the trinity already has tcm support for the 6 speed and 4 speed tranny's...

had it months ago...

you need to update to the latest gm_can_gas crom revision update file available on the trinity downloads page...

make sure you restore original backup to the truck first before you update the trinity...

just loaded the 87 octane tune and when i go into options and information it says pcm 87 octane and tcm original backup
