Are you talking about getting a full tune or just a plug and play type of chip?
If you are wanting to fully tune everything - timing, air/fuel, etc... then you will want a TwEEcer or Quarterhorse.
If you just want a chip to plug in that will raise or lower the idle, open the secondaries sooner, raise the rev limiter, etc.. the you will want to find a LPM and have it tuned to your setup via SHOsource. Several people have LPMs that they will sell or you could just buy it from SS and have them tune it before they ship it.
Dont bother with any of the aftermarket stuff like Superchips or Hypertech. They are generic and designed for stock cars with nothing done to them.
