What is the best bang for the buck performance wise with a 4.6. I have a limited budget (About $250 but can change a little) and my truck is stock.

 

A tuner is the best bang for the buck. I recommend a Troyer Performance XCal2 hand held tuner.

 

Then get E-Fans. I didn't notice a change when I put on a cold-air-intake, but definitely noticed the fans

 

Fans, but get a tuner chip or programmer too and install at the same time, you'll notice alot more power.

 

Those are all great ideas but if the dudes only got $250. or so, both of those cost well over that. Look into an exhaust system, or just a muffler swap. There are some increases in hp and tq but the thing is, with the new sound, you'll think you've gained alot more. Check out Flowmaster and Magnaflow.

Save up a little more and buy a programmer from Troyer. You will see a big difference in performance.

 

Or you could always buy 5 tornados!

 

I agree

 

Go to this sites classified ads, you might find one there or go to Ebay. You might save a few $$.

 

Interesting, can you give me more info on the fans? I installed the K&N Cold intake and noticed an improvement. I am also looking to do the Gibson cat-back exhuast and still deciding on the programmer (which one). Thx

 

You should be able to find an Edge tuner for $50 more in the classifieds or a new one for $75 more. Good luck.

 

75 or 100 shot of nos should pick up racing accleration alot. I wouldnt run it all day long.

you might also look into pulling out your silencer, and modding your fender inlet on your intake. Every little bit helps

Unless you're towing a boat, or have intakes and exhaust and running 93octane, the Hypertech tuner won't make much of a difference at all on the 4.6l. I bought one and tried all different set-ups for 87 octane, they didn't help, I returned it and bought the K&N FIPK, that was better to start with, now when I get my exhaust I might go and get another tuner and see what a difference it can make then.

I think first off you need to ask yourself what kind of "performance" you want to improve. Better gas mileage/horsepower? Faster throttle response? Help us help you by letting us know what you're hoping to gain.

From what I've researched, unless you plan on running 93 or better octane gas, a tuner won't help you all that much. Seeing how gas is near $3+ a gal, I'm staying away from that. Talking to a lot of people on this forum, they seem to agree on that point.
Electric fans(E-fans) are a replacement for your stock fan behind the radiator. Replacing the heavy stock fan with e-fans (usually 2in a set) reduces weight on your engine, thus better gas mileage. You can find them on places like eBay or check out the Troyer website(he gives discounts to F150online members!)
I, like you, am limited on my "truck mod" budget. A replacement exhaust will run you anywhere from $600 up, depending on what/where you get.

Take your time and do your homework, if you hear of something that might give you what you're looking for, use the search engine on this website. Chances are it's been discussed and debated already.
Whatever you do, have fun with it!

 

I got my fans from Troyer ( Dual Derali's with Troyer controllers). I did make a shroud instead of the copper rods thru the raditator. As far as exhaust, I bought a Borla muff. off ebay new for 100 bucks then had the pipes run for about 250-300.
