I've been slowly adding mods to my truck, and although it's not an L, I figured ya'll would be the quickest to answer this.......

So far I have the usual, superchicps tuner, exhaust, AF1 kit, and elec fans.....I wanted to know about changing the pulleys I read all you swapping out. from what to what? what is the purpose, what does it do for you? etc......Does swapping this require a custom performance program, or can I continue to use my tuner?

I've got a 5.4 Screw 4x4, so I'm just brainstorming other options of tweaking a little more mojo out of my brick. Thanks in advance.

 

The pulley all the Lightning guys change is the lower supercharger pulley to spin it faster.

the one for the supercharger...

 

that's what I thought....I was trying to figure it out....you should've seen the look on my face staring inside my engin compartment.......

- Here's my sign:

 

LMAO

 

You can still change out the ones you do have.. wont really be very noticable. It does free up a few ponies from what I have heard though..

 

i noticed a pretty good difference after installing my underdrive pulleys on my 4.6L (i bought Steeda).........no you don't need a re-burn the chip you have should be fine......

 

Thats great!!!!


And yea, give the underdrive pulleys a shot for your truck. They worth a little
