Hey guys, I have a 2002 F150 screw fx4 with a 6in lift, 18in rims, and 35in tires. So far I have put some custom electric fans on it and dumped my exhaust with a Flowmaster. I am wanting to do more performance upgrades, such as... Custom programmer, underdrive pulleys, cold air intake, and 4.10 or 4.56 gears. In what order should I do these in such as which would give me the most power. I just wanna know in what order you guys would buy this stuff in, thanks!

OK - here goes - opinion only !

1. ditch Fffffartmaster - install Maggie
2. Programmer
3. gears
4. CAI - retune (depending)
5. u/d

Reason the proggie is first - to allow for the reqired adjustments for the next 3 items.

 

Well as far as the exhaust goes.. The Flowmaster sounds pretty good with no crackel or anything like that. It doesn't sound the meanest or loudest but I'm not too worried about that. After I do the rest of the upgrades, how muc power do you think I would be pushing out?

 

With all of them, my guess is maybe an additional 35-45 hp.

The gears won't improve your hp.

 

Just joshin' ya on the exhaust - I'm known for this

Flows do not promote the best power production - they actually kill gas velocity / scavenging some ...

Being lifted with bigger meats doesn't help either - you'll be playing catchup here.

Don't expect miracles - even with a 93 octane perf tune. For sure the gears will wake it up (no more actual power, but puts the powerband back where it belongs). The tuner will help with vastly improved shifting, and some power gains.

Good luck

 

you've got a decent list my advice would be to add a shift kit to your list and do the gotts intake mod


MGDan is known for promoting magnaslows yet even he knows borla provides a much better performance muffler but is also higher in price, since your happy with the flowmaster leave it alone it's not like you have a 1000rwhp truck and are needing the extra 3-4 hp to beat a competitors truck...

 

I would go with the programmer last since then you wouldn't have to worry about redueing the costume paart of it (this is what I was going to do when I was looking at more performance.) Well I don't know were Edmound is but were I live the cai (which I have yet to see a real one for a truck) don't do all that much and the gotts was a much better choice, and alot cheaper doing a intake mod will be a great complament to your exhaust. I have heard that gears would give you the biggest bang for the buck with being lifted.

 

You can end-user adjust (on SCT handhelds anyway) for tires & gears, and the idle speed bump for the u/d. For the CAI, you would simply not install it until your custom tunes were ready to flash...

 

With the tires you have, you need the gears bad. A tuner will make you smile.
