Hello everyone, I am obviously new to the site and looking forward to it. I am currently looking to make some upgrades to my truck's performance this year.

I have a 2005 GMC Sierra 1500 Crew Cab 4x4 with a 5.3L and 3.42 gears(here is where the upgrades are needed).

I am looking to upgrade to 4.10 gears this year. Just tired of all the shifting on small hills or when my truck is loaded or pulling my boat.

I am in the Houston,TX area so if anyone has suggestions please let me know.

I have already add a leveling kit, AFE air intake, 295 Nitto Trail grappler tires, sprayed in bedliner, and performance program.

Any ideas you all have I would greatly appreciate it.

Thanks,

 

welcome from just south of houston. one suggestion i would have is to get rid of the programer and get e true tune. its alot better than that little plug in tune.

 

Welcome to pt!

 

What was the performance program you got? and how do you like it? I'm looking into gettting a programmer but am on the fence still...
