Sweet! Got it downloaded & installed. Seems to have worked. I am about to hop in the truck to go run an errand & see how the TCM & PCM tunes work on the road. Thanks again for all the help & the update!

Any word on when a Trinity update for the TCM support will be coming?

Thanks guys!

Yes sir. Will do. Thanks Monte!

I've posted the info on here. I tried the update that was provided by mikel but it doesnt work with my truck. In addition to the adjustments, I also intend to change out the tires to larger ones and want to be able to compensate for that as well.

I was planning to firm the shifting and potentially change a few parameters, I am not sure how this will effect the tune if I have my custom tune done before adjusting. Probably better for me to wait until the TCM support is out and can be adjusted if needed. If I am wrong please correct me though ...

How often are the updates done? Would i be better off allowing my tuner to do the custom tune now or waiting for the update that has TCM support for my vehicle? Thanks

Okay. I'll keep checking back for it.

Thanks.

Let me know if there is anything I can do or if there is additional info that I may need to provide.

Thanks.

no worries, I appreciate you guys trying to help me out. I will try to keep an eye out for it. I am waiting to do the custom tune until the TCM can be adjusted as well.

I tried to use this update a few times but it doesnt seem to take. When I install a tune to the truck after update it still doesnt allow any TCM adjustments. Not sure if I installed it correctly or if its just not the right one for my truck.

OK, so I recently got a trinity for my truck. I intend to put a custom tune on the truck with some other mods (K&N 63 series CAI & Cat back exhuast)

I have installed the CAI & exhaust and the "87 Octane" tune from the Trinity, However, when I pulled the files off the Trinity to send for the custom ...
