September 26, 2008I have 2001 F150 with a 4.6 V8. I have the procharge D1sc running 9 psi of boost, 42lb injectors, ngk tr6 plugs, SCT MAF, and a custom tune.
Currently i have one flowmaster 40 series for exhaust, the truck feels like it needs more flow, and i also think that the cats are clogged up.
So what should i do? New stock cats and a true dual setup? ORR?
Also, i need a new lower idler pulley, the lower smooth pulley, where can i get one?
