Hey guys newbie to the forum, post over at chevy truck world sometimes though they love their westers but anyways i was wanting to know all the info about a nelsons tune for a 99 4.8 such as what tune to get, what numbers i should expect to see hp/tq, if i should use a shift kit and a corvette servo, and i was also wondering about stalls ive heard i should get a 3000 stall and where to get it and all these others? id also like to know about my gears their 3.42's is there a way i can swap em out for 4.10's? Thanks, and all help is appreciated
