Programmers for towing 4.8L
#27
I pull a trailer that is about 8000 pounds loaded with my 07 Sierra 5.3L. It has a very hard time going uphill. I am debating between buying a heavy duty gas or diesel truck or investing in some upgrades.
So far I am thinking of upgrading gear ratios, intake and exhaust, transmition oil cooler and oil pan, and wondering if I should get a programmer as well.
Any thoughts or experience to share on any/all of these things?
Thanks!
