Performance and save gas just doesn't really seem to go together.

Check into a performance chip.

The first step to answering your question would be to get a clue as to the function of vehicular powertrains.

lolololololololollol

but to answer your question...

You cannot help performance and save gas at the same time. If you want to help performance heres some of my suggestions.

1. get the U-bend replaced with a straight piece of pipe.

GM decided that they wanted to mount the rear O2 sensor vertically which results in the picture below. Replacing the u-bend will free up some HP.

2. Get a CAI or FWI (fenderwell intake)

Id suggest the NAIOA FWI, but I think they stopped being made so they may be hard to find.

3. reprogrammed PCM.

They're only $100 and its well worth it from what I hear.

PCM

Contrary to what appears to be popular belief, modifiying a car for performance purposes, will quite often improve efficiency. If a simple bolt-on worsens your economy ratings, then you lost some power. When a car makes more power, the engine is under less stress at cruising speeds, and is usually at a lower RPM. The threshold at which, this usually changes, is when you have to modify the fuel system. By modifying the fuel system, I mean making the AFR richer to support modifications. A good intake system, a decent exhaust, and some good plugs/wires should help wake the car up a little, and actually improve mileage, as long as you drive like a civilized human being.
