My trinity will be arriving in a couple of days and after downloads and registering it where should I start? what is the basic or 1st tune you would do?

What vehicle, and what fuel do you use?

Thanks

How do I know when I get a response to my post? I didn't get alerted or a email.

just have to keep checking back, or go to your user profile and select to receive email notifications...

for that truck, if you use 87/89 octane gas, then install the 87 Octane Tune..

if you use 91/93 octane gas, then install the Diablo Tune..

and for the tranny tune, select Firm Shift..
