I have an 07 new body style gmc single cab with a 4.8 and I'm thinking bout installing a underdrive pulleys set. Just want some feed back on the pros and cons. I already have a programer,headers,exhaust,and air intake. Hit me up. Thanks Leonard

 

Welcome to the site!!
I just left from PL about a month ago


Id skip the pulley and get a tune from Pat-g there in town or even a cam swap..

 

Get a custom tune and ditch the programmer. Also if you want some real bang for your buck, Get a 3k stall from circle D.

 

Def ditch the programmer, get a 3000-3600 stall with a good cam and custom tune and it will be a completely different truck.

 

Welcome!

 

welcome . . .

Make the pulley your last mod . . . spend or save the money for a cam swap.

 

Right down the road from you in Lolita

 

Welcome. I was thinking about pulleys too. I got a 4.8 so I'm interested to see what they would do.
