Get tractions bars, ajustable suspension blocks if allowed, weight in bed so your full weight, drop fronts to 25 psi, front locker, and some electronincs to get your defueling moved up to 3200 rather than 2700.

rules say no traction bars or blocks you can put weight in the bed my truck doesnt defuel till 3300rpms since i have a hrvp and quad boost fooler i run 2950rpms down the track

do not run 2nd hi. I have heard from tons of guys that 2nd gear is very weak. I would try 5th low.

ive heard not to run high side also but guys alot of guys do it i think if a can get a little more power i might try 5th 4low but thats a big jump from what i am using now my next pull i can make is the 4th and i think i will either have a cam or a redline by then so maybe one of those will help just curious about tire pressure with these procomp mts prolly try 20f 40r
