99-03 C5 Diablo Sport Predator Tunable Programmer

The Predator Performance Programmer allows you to make custom enhancements to your Corvette's power management system. You can adjust timing, fuel enrichment, rev limiter, electric fans, and even shift points and firmness on automatic transmissions. If you've changed your gear ratio or tire sizes, the Predator can correct the speedometer reading for ratios up to 4.56.

The diagnostics package is identical to the GM Tech 2 system. A detailed instruction manual is supplied for this plug-in tool, and it is backed by a manufacturer's limited lifetime warranty.
