depends on the status of your vehicle, what you're looking to achieve and what you consider "cheap". first thing I did to my truck when I got it home was change all fluids, air filter/fuel filter change, replace injector o-rings and that BB mod, probably cost me about $350. spent a year slowly troubleshooting what ended up being 2 dead cylinders then pulled my motor and rebuilt it.
there is also a sticky on this too buddy.

Reason: remembered something
I plan on changing all the fluids i owned this truck a few years ago and just bought it back so i just changed the filters and fluids so want to do some upgrades that arnt going to be thousands to do..
I would start with the 6637 air filter, a valve body and a mild tune. That should wake it up a little. That, of course depends on the overall status of the truck. If it's time to replace/rebuild things. The tune and valve body will just break it faster.
