I pulled the trigger on the pro charger p1 tunner kit with one size smaller pulley and some pacesetter ceramic coated longtubes! Should be good for about 10lbs of boost and hopefully 500+ wheel HP. The kit produces 416 wheel HP on 8 pounds with prochargers canned tune through stock exhaust and manifolds. We will see I guess. Does anyone know the fuel limits of these trucks without a cam upgrade?

Nice. What fuel will you be using e-85 or premium.

Just good ole 93. E85 is pretty much non existent in south ga.

A bunch of '14 5.3's over 500rwhp? Didn't know that there were that many already up there. I know that some sort of cam swap followed closely behind/during testing of some shops turbo kits, simply because of fuel issues...simply due to the fuel pump lobe...I would like to know more about fueling these DI engines for the 500+ rwhp ranges as well.

Check out sinister. Their bolt on turbo kit puts over 500 to the tire. Stock engine, fuel, Trans... They did a cam swap and converter in the shop truck just to push it even more but they have a ton of 14 trucks w turbo kits.

I had no idea. Dang these new 5.3's are more sick than I thought. Maybe I need a procharger on mine. I wish my finances were better, though...
