S10 Prom Ecm Flash?

I was wondering if anybody has flashed their ECM chip to get better gas mileage and a little performance. Any info on where to get it done? And how much of an improvement are we talking about? Post some of your gains if you done it before. Gas prices arent getting better around here...
