CAI, gears, LSD, exhaust (headers??), tuner, ECT. The question is which do you wanna do first because eventually you will do them all if you are like most of us here. LOL

Take the throttle body spacer out (actually losses power for you on a modern throttle body), ditch the flowmaster 40s (great sound, but the chambered design flow much worse than even stock). Ditch the 22" Wheels for something with less weight.

Even though it doesn't add any HP or Torque, you are not going to see much in the way of 1/4 time gains until you re-gear that thing with 4.56 gears. A better aftermarket torque converter would be imperative too. All the performance mods you dump money into are just losing 25% or more before they reach the rear wheels because of the stock torque converter.
Fix the gears and torque converter first, then you can concentrate on mods that make more power like headers, cam, custom tune, heads, etc...

Another piece of wisdom from the wise Hammerson! AAHH little Grasshoppers heed the wisdom!

Upgrades
77 series K/N intake
Super Chip Tuner
3'' True dual exhaust-
-Dual Flow master 40's
Air AId Throttle Body Spacer
22'' Boss Rims

my tuner is the only thing that i noticed a increase with power. The order i lined them up is the order i installed them. And my truck only runs 16.6 1/4 mile at 87 mph. ANy one have info or ideads please let me know.

That time seems slow for that list mods. Personally, I think that if you are looking to increased performance you should ditch those big rims. The added rotating mass is not helping your times.

Not really. if he has lower profile tires, those aren't heavier than 20's with 33" rubber because the loss of rubber offsets the rim weight. i would guess 5lbs difference at most between stock 20's and 22" SRT size.

You say True 3" duals....You got Long tube headers? Do you still have the factory Y-pipe? Then it's not True Dual. i dunno why everyone thinks that is true dual?
Anways, that 3" doesn't help much because the factry y-pipe is only 2.5" AND it has a totally Smashed merge pipe which hinders flow.

Get yourself some gears, Headers, Cam. Those 3 will drop your times significantly.

well ya did buy a truck, not a vette or viper. that does seem a little slow, and like everyone else said, if your worried about quarter mile times 22's are not the way to go

[dunerider650]

get rid of the big rims...and if you are running true duals SPECIALY 3" your loosing power ditch all that.

[lxman1]

Put 2.5" dual exhaust on it and it will be better than dual 3". Too much of a good think can kill you

[truckin151]

First off you have a heavy ass truck, not a carbon fiber sports car so you need to tune it for more low end than top end to get the truck off the line and out of the hole faster. Gears for sure will help change that torque curve a bit to the low end 4.10-4.56, then an aftermarket converter to get rid of a hell of a lot of loss through the drive train and help get the power down to your wheels a lot better over stock. After that some headers, cam, heads, a proper dyno tune and a more free flowing exhaust to make the true duals work to your benefit.
