Proecm Mod tell me more...

I was doing a little research and wanted to know more or if they even sell this chip anymore and if its even practical.. I was looking into doing this and eventually an Intake and im doing an exhaust shortly after I get my inspection (Next month..). I feel for the money maybe a cold air would be first, depending on what one works best then the chip? More air + more fuel+ more breathing should be good maybe headers eventually too..

I know its no WRX, but with handling and a little more power and rumble it can turn just as many heads..
