Bb Tune And Exhaust With 4.8l 3.42 Gears

[bc_gavin]

anyone know if i was to get a blackbear tune and a duel exhaust system with a 4.8L and 3.42 gears would make much of a diff, or should i get my gears upgraded first im only running 33's

I'm sure it would make a difference. As far as gears it's prolly better to change them before the tune, but don't think it matters. If you get the tune 1st just let them know what gear you will be changing to.

what gears do you think would be best fitted for 33's?

I assume you have 2wd since you do not already have 3.42. I have the 4.8 as well, and 2wd, I put 4.10 gears in. Did that before the BB tune.

i have 4wd and 3.42 gears/ i was wondering if i should upgrade my gears to run 33's and a tune
