Depending on the health of your tranny, level 3 or 4 will be all your tranny will hold without limping. In my wifes 01, level 5 will limp the tranny every time on 4-5 shift after smoking tires through 1-2-3
Level 4 has limped the tranny a couple of times but is typically a good tune.

A transgo shift kit and converter will help you hold the power very well.

14's in the 1/4 if you have tie-rod sleeves and launch in 4x4 (assuming you have a 4x4)... if you don't have the sleeves don't bother running it. If your truck is 4x2, get good tires or don't bother running it

The PPE is rated as follows (at the crank) subtrack around 20% or so of that for a rwhp estimate

LVL.....HP.....TQ
1...... 40..... 97
2...... 90..... 160
3...... 120.... 200
4...... 160.... 240
5...... 225.... 335

All just estimates, trap speed and weight will give you a real hp number.

Be careful above lvl 3 on the stock 5 speed

People been known to run low 14s. With a good tuner, or efilive. And bolt ons. Tierod sleeves and lower your torsion bars and you should be able to net atleast a 1.8 60ft putting u into sub 14s. I know way back when, when I had my 06 lly with a quad stealth 2 tuner on a 70 hp tune in 2wd I ran a 14.5.
