Program your own chip.
Or call Johnson Motorsports. I think it is JMSCHIP.com or something. A friend uses him to burn his custom chips. Like $250. He now puts reliable 505 to the rollers. And drives like a new Saleen. It is a 95 Cobra with S/C and other mods. Reburns are free.
I use the EEC Tuner. I have a topic on it already.
