Performance mods for 4.6

Intake: Gotts mod, Headers: Aren't really any LT's for the 4.6L so don't bother. Exhaust: won't be that great of gains, do it for sound. Programmers: https://www.f150forum.com/f2/tuner-134091/
Efans would also be a good mod to add to the list.

Pacesetter makes long tube headers for the 4.6L. You can find them at autoanything.com and summitracing.com. I'd imagine there are a few other sites that sell them but those are two of the ones I look at regularly.

pacesetters are garbage imo, just personal experiance. gibson shorties are supposedly a good 5hp or so...but these trucks and the pos studs make it not worth it to open that can of worms...again my opinion. efans are cake, and the best mod i have besides my gryphon. everything else is alright. the throttle body spacer is a paper weight...i wouldnt run one.

Gotts, siso exhaust, programmer, efans. Not enough, gears. Your hp is not going up dramatically, you will optimize what your already have with a programmer. Gearing will allow the engine to get into it's upper torque and hp curve quicker. So you really have not added hp with the gears, it just feels that way until you get on the highway. If you wanted some more power, the you should have gone 5.4. And lets not even think about the paper weights!

efans do a search on the forum, or a google search for write ups.

What efans are you running? Is the gryphon a version of the edge evo?
