I'm pretty sure since the reflash version can out the stock limits at 8500rpms and the racing limits at 8600. Not exactly sure what the difference is, but I guess since the stock ECU is designed for stock-class racing you dont need to run a aftermarket ic since it isnt legal and I think the racing ECU its highly recommended.

The stock class ECU is meant for those guys racing stock class and not running an external intercooler. It's fuel/timing curve is much less aggressive than that of the Racing ECU.
If you plan on doing extensive modding then the Racing ECU is what you want. You want to have a minimum of an external intercooler to run this ECU. Since the rev limit is set at 8600 you will want to ensure you have your prop pitched to limit RPM's to 8350-8400 with the stock valvetrain. Later you can do some headwork and benefit from the higher rev limit.
The Racing ECU makes TONS of power!!
