“Blower is there for show”

 

Buy a dragy. Run your truck a few times with it. See your average mph. Go to Wallace Racing calculators. (its crank hp) they say 90% but that's for manual I'm pretty sure after checking it for years. Find 1/4 mi. stats. enter your weight and mph. See result. Multi by about .8 for an AWD and 4l80 or .85 6-10 spd for 2wd RWHP. It is pretty accurate actually over and over for late model stuff. Have fun. Even if is not exact although MANY times it almost is, it will tell you a lot. Very best of luck. Enjoy. playing with the #'s.

Gears. Next step should be gears. 4.56 is fun with a heavy 4wheel drive.

 

Being as mine is a 2006, it's 2x4.
