Unless you spend WAY more money its tough to get a big HP gain. Then again the beauty of these low power engines is they don't break.

 

You might be able to squeeze a bit more power out of it by advancing the timing a few degrees. You'll probably need to use premium gas and have a functional EGR so it won't ping. I run 3 degrees advanced from specs, that's the limit for passing the smog check in California.

 

Need more power change your gears.

Do a swap to a more powerful engine.

Strip all the un needed weight out of the truck.

Horse Power gains in a 22R series engine are very expensive for little gain

 

Huh.......5:29 and 33's = a million HP

 

Maybe just run it at a higher rpm. When are you shifting?
