well its about that time after doing some performance mods and such and such its time for a tune on my 2007 nnbs rcsb 4.8.

so what are my options for a tuner and what are the pros and cons to the tuners out there... i had a handheld but now i want a custom tune.

get with blackbear or nelson if there is no where to get one locally. they do really good work

so as of right now i have a 3.73 rear gear and i plan to get the tune in next few weeks. after i get the tune i plan to upgrade to 4.56 gears will i need a re-tune?

I have the same truck & got tuned by Nelson. I was really suprised with the performance gain. It made quite a noticeable difference.

I got black bear tunning.... And it made a lot of difference coming from
Being superchiped
