Try www.motorhaven.com for a chip.

Here's the exact url to go to. Scroll down until you get to the bar with the hp/torque gains and match it with your engine. I have a 2003 with a 4.2 V6 that will get about 20 hp's with the chip alone.
Good luck

Re: 2003 stx
For a 6 cylinder there isn't a Superchips Microtuner so the best option is a DiabloSport chip. We program it to boost performance and driveability. Any gas mileage increase is a side effect of the added power, but you have to use premium fuel with the chip so most people end up breaking even on fuel costs.
