Performance Modifications for Ford F150 5.4L Triton Engine

Just my notes...........



Steve’s Summary
Figure out what mods you are going to make before buying a tuner, since you may need to customize the tune based on the other mods.

1.       K&N Air Filter
2.       Throttle Body 80mm ( 10 to 15 HP) Performance Power-Plus throttle Body $320
3.       UnderDrive Pulleys (8 to 15HP, 12HP, more with Tuner)
4.       Electric Fans
5.       Headers, if doing at all, do long tube headers.
6.       Tuner - customizable

Not researched
Throttle body spacer
Tuner above, requires custom tunes created by “local tuner expert”
RE throttle body
wondering if the added horsepower/torque is moved up the rpm range? looking for more low end torque for towing.
Asked by: Greg - 10/25/2015
Customer AnswerWhen installed on its own, the throttle body does tend to skew horsepower and torque higher into the rpm range, though once you start throwing other modifications and tuning at your truck, the range tends to normalize. However, the best upgrades for low-end torque on the 5.4L F150s are long tube headers, a matching mid-pipe, and appropriate tuning.

Troyer Performance numbers for the following:

Pulleys: 11.8 HP with stock settings – 14 HP with a Superchips programmer. Don’t know the numbers but I would guess you’d see similar numbers with just about any programmer.

JBA Headers: 4.6L = 13 -15 HP, 5.4L = 14 – 17 HP

Cats: No numbers given but Troyer states that the Magnaflow cats they sell can support engines making over 800 HP. They also say that these cats cheaper ($$) than OEM.

Other items I am considering at some point down the road along with the above upgrades:

1) Y-pipe – kind’a complicated but would free the exhaust up even further with the headers and 3.0” cats. Probably should have this done in a muffler shop.

2) 75mm throttle body would also compliment the K&N FIPK intake.

Just my two cent everyone but would stay away from headers unless your putting on a major power adder. Stock exhausts are prettyy good and a swap is really just for the sound on a basically stock truck. Had a friend put shorties on a 01 5.4 and after he ran .1 better on a gtech. Tried it before and after.... not alot for the 500 bucks.

Long tub hoarders not shortys. Pacesetters are a good one to get, 1 3/4 tubing with 3" collector can get for around $250
Two things come to mind, first electric cooling fans and under drive pulleys. Now, for some plain general stuff, clean the MAF sensor, clean the throttle body assembly, use a good injector cleaner like "SeaFoam".
And, you could add a high flow air filter.

Where is the best place to start looking for underdrive pulleys and e-fans? Do you guys think someone that isn't that good with vehicles can do either of those, or should I take it to a good mechanic?

Thanks for all the info everyone, this site kicks a**!!!!

While a cold air intake is nice, by far the mos effective power upgrade for your 2004 to 2008 F150 is PCM tuning, and we here at Stage 3 can provide tuners from some of the best names in the business, as well as even more potent custom tunes from 5-Star Tuning. A performance PCM tune works by changing key parameters of your truck's Powertrain Control Module, adjusting things like fuel curves, ignition timing, shift points, and other computer-controlled functions of your engine to help your truck get improved horsepower, torque, fuel economy, and transmission function all in one go. Most tuners come with fairly standard "canned" tunes that are pre-built for use with just about any truck that the tuner or monitor is hooked into. A custom tune is a whole different animal and is specifically programmed for use with your particular truck. Our custom tunes come from 5-Star Tuning, one of the leaders in F150 custom tuning, and their custom tunes can be built around both your preferred fuel octane and application to get you the perfect tune for your aggressive truck.

The last of the "first" modifications is generally a cat-back exhaust kit. While a 2004 to 2008 F150 cat-back exhaust system generally won't give you much or a performance gain, they do give your V8-powered F150 a very impressive sound. We here at Stage 3 carry both single-exit and dual-exit cat-back kits for your truck, all of them from some of the biggest and best names in the performance exhaust industry. We have kits that can give your everything from a mellow purr to a ferocious roar so that you get the exact sound you want for your custom F150 build. We've even done an impressive amount of our own exhaust system testing on our 2004 Project truck. Check out the videos below:
2004 to 2008 F150 Lighting Components and Upgrades
If there's one thing we have plenty of for the 2004 to 2008 F150s, it's lighting parts, and these truck's respond remarkably well to a wide range of aftermarket lighting components. Our very own 2007 F150 Project truck is decked out with a complete Recon Smoked Lighting Package that consists of new headlights, taillights, and a third brake light that give your truck a total overhaul and makes an excellent platform for future lighting upgrades and other exterior accessories. If basic replacement lighting components still aren't cutting it for your late-night trail rides, then check out our impressive selection for Rigid Industries Off-Road LED lights and light bars. We have Rigid Dually Lights, D2 Lights, E-Series Light Bars, and SR-Series Light Bars all in different size and lens configurations to meet your truck's off-road lighting needs.

Lift Kits and Suspension Upgrades
Want to turn your 2004 to 2008 F150 into a brutal desert runner? How about a potent rock crawler? Or do you just want some extra ride height to fit on those 33" tires? Whatever your reason, we here at Stage 3 have you covered with a ton of lift and leveling kits from some of the best names in the business. Spacer Leveling kits are our most popular suspension modifications and get rid of your truck's front rake and let you squeeze on slightly larger wheel and tire combinations. Coilover Leveling Kits do the same thing, but also give your truck better off-road performance. For anything else, there's our selection of complete suspension lift kits. Lift kits are the go-to options for getting your truck higher in the air and fitting on truly massive wheels and tires. Our current lineup of trucks have all been graced by lift kits of some sort. Our 2005 F150 Project Truck has a Zone 4" Suspension Lift Kit, our 2004 F150 Project Truck has a Pro Comp 6" Suspension Lift Kit, and our 2007 F150 Project Truck has a Zone 6" Suspension Lift Kit. The end result on all of these trucks was nothing short of incredible, and the lift kits, wheels, and tires dramatically changed their looks for the better.
