Before i get yelled at my search button doesn't work i was just looking for wrong info. My fiance and I purchased a 03 lightning and i'm looking to purchase a 4 lb lower pulley, what all supporting mods do i need? It already has cai, dp heat exchanger, borla cat back, ftvb, and i have a line on a home ported blower that i may add at the same time. I plan on a tune but wasn't sure if i would be maxing out the maf or fuel pumps.
