My buddy has a 2003 silverado and he just purchased a Kenny Bell blower (roots blower). The kit comes with injectors and street tune etc.. But, I was wondering what fuel pump he should upgarde to, even tho the kit doesn't recommend it. We may get a smaller pulley to increase lbs so we might as well have a higher flowing pump... Any brands etc. walbro make a 255 pump for the silverados... Anyone with this kit???

Thanks Mark Tisdale

btw would you all recomend him going to a step colder plug(ngk tr6) compression I think on the 4.8L is aroudn 10-10.5.
