I'm looking to either get some headers next or the pulley \ belt kit next. Which one would you do next and why?

 

Do you have a programmer yet? I would get that first.

 

I would get pulleys before headers if those were the two choices.

 

No programmer yet. I was thinking of getting the programmer next to last since it will be fine-tuned to accommodate the mods that will be installed already (i.e. headers, exhaust, intake, etc.).

 

What does the pulley kit do exactly? Is it any better then stock pulleys?

 

The pullies let the crank turn the accessories easier than the stock pullies, plus they're light-weight which helps with the ease of turning them. This is probably the most noticeable upgrade I've done to my truck............and I've done a few (not all).

 

There is hours of reading here on pulleys.
