I am wanting to find some affordable upgrades for my 01 f150 w/ 5.4l triton. i put 315's and lose some power and i want to try and regain some of it.

 

everyone on here will tell you a tuner... and they work... then get an exhaust and intake

 

i already have a cat back exhaust with 40 series i was really interested in an air intake ne suggestions i have also thought about a tb spacer is there ne real performance gain.

 

dont waste your time with tb spacer if you want a intake get a k@n or af1 ther about the same a tunner is the best bang for the buck then gears and e fans thats what im doing next to my truck and it runs good for heavy slug talk to mike at Troyer Performance he will help ya

 

TB spacer imo is a gimmick item.

gears will give ya some pep back, you went with 315's and you plan on staying with that size tire?

i think a lot of people run 4.56's with a 315/35" tire...
im running 4.88's and intend on running a 38" tire.

 

that all sound really good thanks alot but what do yall think of high flow injectors i heard so people in a different thread talkin about them and are the really complicated to install.

 

pretty basic, straightforward install. arent they really only needed for turbo or supercharged applications. dont think you really need them unless youre going to put more air into the engine.

 

d0 what I did in my sig

 

I agree with what has been said by the members.I have a 2002 Ford F150E/C stage2 Roush.It came with a 5.4 with Roush cold air intake and Roush cat back exhaust.The first improvement was a set of JBA stainless shorty headers,next was a superchips programer This really woke up the truck.After all this I installed a Vortech blower.Now the fun begins I liked what the blower did but i had to reset my ecm back to stock so vortech could put there program in it.Do not like thier program so I called Troyer Performance and mike and I set up a program for the truck(waiting for it to arrive).Do not install any hiflow injectors unless you are going to turbo or supercharge.If you are looking for nice gains go with what has been suggested you won't be dissapointed.Good luck. PS.I have my superchip programer forsale
