I have a 2003 ford f150 5.4 with a 2 inch level and 35s with 3.55s and its pretty darn slow, I'm 17 and can't fork up 1200 for new gears at the moment, I am working on getting a custom tune from mike at mpt soon, I have done the gotts with silencer delete mod, and have a drop in k&n filter, I have true dual rear cats deleted with dual flowmaster 40s, I am thinking about electric fans and underdrive pulleys, I would want feed back from thos who have them, any other mods would be great to know,
Thanks,
Nick

I have same tires, gears, and engine and I just bought an SCT SF3 and gained more power and mpgs too. You cant get a custom tune without a tuner though...

The gears are gonna be the only real difference maker though bud.

Yeah I'm getting the sct from mike at mot soon, thanks for your help

So buy the gears/install kits and learn to set them yourself. You can learn lots with google

There's no such thing as a cheap power adder. Specially with that tire/ gear combo. How fast do you really need to go?

Loudnproudford

Not super fast, just a little more umph

Anybody else?

Since you don't want to do gears (which is the only correct way to do what you desire), I'd suggest 33's.

The SCT is the best bang for your buck. It will help to counter your tires and you should have a little more HP than you did with the stock tires. Keep in mind, however, 35's put stress on the tranny with 3.55 gears. I wouldn't be hammering on your truck without throwing some 4.10's in there.

Edit:
Any older truck is lible to break if you hammer it, even with proper setups.

Even 33's rob power. That's what I have for winter tires and it's not much different than my 35's.
