1997-2004 C5 Corvette DiabloSport Predator

What is the Diablosport Predator?
The Predator is a state-of-the art, high performance tuning flash programmer in a sleek handheld design. Once connected to the vehicle, the Predators internal computer recognizes the vehicles PCM and automatically picks the proper tuning files designed specifically for that _PCM. Inside the Predator's memory are the actual tuning files that optimize spark timing and air/fuel ratio curves. Unlike other 'tuners', DiabloSport's programming is performed in very small increments throughout the entire RPM range, for a smoother, wider and a more predictable power delivery. DiabloSport engineers spend many hours on the dyno, street and track to ensure the tunes provided with the Predator are the best they can be.

Dyno Tested Performance Tunes
The Predator was created with one thing in mind, POWER!

Average power gains are per tune. The Predators additional power makes itself noticeable immediately with an increase in power that starts in the low RPMs and builds into a frenzy at the high RPMs.

A Predator equipped vehicle will notice significant improvements in drivability. The additional power created by the Predator tune will yield quicker acceleration and better mileage, whether it is in town or out on the highway.

The power increase in the lower RPMs will yield a better throttle response. The increase in MPG is a byproduct of maximized engine efficiency, the improved timing curve and air/fuel ratio creates a more complete combustion, i.e. the engine extracts more power from each molecule of gasoline.

User adjustability. the user can set their own parameters - Choose from DiabloSport's performance program, have a custom performance program made for you by a Diablo Tuner, or create your own:

a. Richen or lean fuel mixture
b. Advance or retard ignition timing
c. Raise and lower shift points in 10 RPM increments
d. Raise and lower rev limiter in 10 RPM increments
e. Reduce shift duration (time delay during gear change) (+/- 25% and anywhere in between)
f. Increase or decrease shift firmness (+/- 25% and anywhere in between)
g. Correct speedometer for gear changes and/or tire sizes
h. Turn on cooling fans at lower temps in incremental steps of 1 degrees (for vehicles w/ factory equipped electric fans)
i. Adjust top-speed limiters

The Predator allows the end user to adjust the following parameters:
*Timing Table 2000-4000rpm (+15/- 20%)
*Timing Table 4000-7000rpm (+15/- 20%)
*Fuel Table 2000-4000rpm (+/- 20%)
*Fuel Table 4000-7000rpm (+/- 20%)
*Idle (+ 500rpm / -300rpm)
*Speed Limiters (Trucks Only)
*Rev Limiters
*RPM Shift Points
*MPH Up and Downshifts
*Shift Timing
*Shift Pressure
*Cooling Fan ON and OFF temperatures
*Re-Calibrate Speedometer for Gear and Tire Size Changes
