I have a 2001 Supercrew 4X4 with the 5.4. I need more power out of it. When I upgraded to some bigger tires (295's) it got even worse. It's completly stock right now. Is there a tuner or something for these trucks? No superchargers or anything like that. My mustang is already supercharged but need a lot of help when I have to tow it. Any help would be greatly appreciated!!!

 

Fresh tune up... fuel filter... Search "gotts mod" for an pretty cheap air breather mod...You can get a tuner or programmer ... Alot of guys use the gryphon

 

Otto's helpful guide to getting the most out of your truck. Steps should be done in this order to achieve the best results.*

*Warning* Proper maintenance should be complete prior to mods. Results may vary. Just because I list these things doens't mean this is all there is to do. These are just a few of the more cost effective mods. It also doesn't mean you'll see huge increases in mileage. Power mods do not always net mileage gains. Driving habits largely dictate mileage.

1. Gotts mod with a dry flow filter (Amsoil nanofiber, aFe Pro dry, WIX)

2. Muffler swap (most cost effective) or custom cat back system with a straight through muffler (Magnaflow, Borla, Dynomax bullet, etc). Depends if single or duals are wanted for details. Full exhaust system with headers can be done also.

3. SCT x3 or Gryphon CS/CTS programmer with custom tunes.

4. Electric fan conversion. Can use a custom system or kits such as the one in the link below.

5. Gears. For slight changes in tire size this is not a cost effictive mod, especially with 4x4. It will give better towing capabilities and take stress off of the transmission. Most don't change gears until the tire size is over 33" or they do heavy towing.

 

Don't mean to be a thread jacker...but If I'm planning to install e-fans and do the gotts mod soon...should I wait to get a tuner with custom tunes after those mods are completed, or can I just tell the people from VMP that this is what I'm planning to do to my truck in the future, and they can set me up with a custom tune before those mods are completed on my truck?

 

Efans don't need any adjustment in tuning. It's just nice to have the programmer to monitor the temperatures when getting the controller set up, as the stock guage doens't give a good degree reading. You should mention the Gotts to VMP when you order your tunes, and then do the Gotts when you get the tunes. You can do it before you get the programmer and be fine.

 

Any difference between going with VMP and PHP? I see you went with PHP.

 

I want to use the Magnaflow single in/dual out muffler. Should I replace the stock cats with some hi-flow one's? How many cats do these trucks have

 

If you want a SCT device, go with VMP. If you want a Gryphon device PHP is the only way to go. You can get SCT calibrations at PHP also. My suggestion is call both places, talk to Bill and Justin, and see which one you'll feel better about going with.

 

The cats really aren't a large point of restriction, so no need to remove them unless you want more sound. Your truck has four cats, two on each bank. My suggestion for a SI/DO system:
1. Replace the stock Y with a Magnaflow Y 2.5" in 3" out. See the picture below why the stock Y is a point of restriction.
2. Add a 3" mid pipe to the muffler.
3. Install the muffler as far back as possible to reduce drone.
4. Add dual 2.5" tailpipes to the exit location of your choice with the tips of your choice.
