Got a buddy with a 2003 H-D F150....real nice truck.
Anyways, I'm talking him into getting a smaller pulley and tune.
So far he's gotten a drop in K&N filter....
But how about pulley size? I take it that the stock HD pulley is larger than the Lightning Pulley? If so, how much boost will he be pushing with the 2.93 pulley swap? Would it be better to go down to a 2.80 pulley?
Thanks for your help
