Hp tuners (12'sierra5.3) help

['12sierra5.3]

My first post so be merciful. I just got my Mvpi2 yesterday. Downloaded my stock tune stored in a safe place. I turned of AFM (d.o.d) and changed my tire size. But now I'm trying to get into actual engine tuning. I want to turn off most of the torque management tables off. And mess with PE. I daily drive my truck, pull my single axle camper up the mountain (13% grade in some spots) every weekend to camp out. I just want my truck not to be gutless below 4,000 rpm and lanch good from a stand still, also able to power brake a nice burnout every once in a while. So if anyone have experience with hp tuners and tuning 09-13 trucks input would be awesome Thanks guys!!!
