Install a pyro, first thing.

On the IP, the passenger side bottom there is a black triangular cover. Take all but one bolt out, just loosen that last one so you can swivel the cover out of the way. Rotate the engine until you can see (might need a small mirror) and allen screw. Take a brand new 5/32" allen wrench (no rust can fall into there, so only a new one) and rotate the screw clockwise to increase fuel, counterclockwise to decrease. A little goes a long ways. Start with 1 flat, which is 1/6 of a turn.

Whats the soup bowl mod? just asking? Where would you get a pyro from?

Take your air cleaner off and remove the "soup bowl" on the inside of the lid.
An exhaust will help but the order don't matter, just make sure you install a pryo before playing with it.

So, i dont know how to get the metal soup bowl part off. I took out the rubber plug in the side and the plastic pipe that goes in the bottom of the soup bowl. Do I have to break or cut the soup bowl itself off. Just dont wanna break my truck and make my dad very angry

I used a dremel and cut mine out. Then grinded everything flat so no metal flakes fell into the intake. then painted it all.

Yup, your going to have to cut it off.

FYI, that mod kinda dyed out, as a guy Dyno'ed his truck with and without, and it didnt make any difference.

You can get a pyro from anywhere, just make sure its top quality, ISSPRO, autometer, ect
