Hey there Ivan, welcome to the site. You got the best color by the way.

Now, PLEASE read through this link and all its contents of the most popular and worth while mods for our trucks. It'll keep you from making posts like this one that have been covered many, many times before.

Another great resource would be to read through some, or all of the big build threads on here, a lot of them will explain and walk you through various upgrades and modifications.

HAHA oops, :caked: Thanks for the heads up Brian!


I think he is talking about the Intake Resonator Box, but its hard to be certain.

that thing, not where the filter goes. i've read through some of those tutorials and didn't see anything about free or cheap horsepower gains.

Ivan,

It's going to be hard to add power, really.

Deck plate, ISR, elbow removable, and a more beefy soundin muffler will give you the biggest illusion of power, for your buck.

For any real gains you'll big looking at good bit of money, and a good bit of a PITA. :-)
