These DiabloSport II hand-held programmers from SLP feature exclusive SLP custom power tuning. They include user-adjustable features, trim air/fuel ratio, and spark advance, and they eliminate power enrichment delay. They also function as scan tools to read engine diagnostic codes and engine outputs. Models are available for several applications.

Looking for the most powerful PCM-tuning tool on the market? Unlike typical off-the-shelf programmers the 1999-2002 C5 / Z06 Corvette DiabloSport by SLP comes armed with ultra-hot custom tunes (replacing the Standard Diablo Performance Tune) developed specifically for your C5 or Z06 Corvette.  The Z06 Tunes include SLP’s Performance Tune matched to Long Tube Headers. Through extensive testing on their in-house dynamometer their engineers were able to determine the precise levels of spark and fuel required to achieve optimal horsepower and torque at each rpm increment. In addition to its dyno-proven performance programming this portable easy-to-use unit allows you to fine-tune a wide range of computer-controlled power train functions for maximum power and drivability if adding parts. Each custom program has ignition timing and fuel optimized for each package allowing you to plug in the tune download the tune and hit the street.

Tuner Characteristics -

- Screen Size is 300% larger than the competition
- Ability to have customized programming which can be done via email/internet (see below**) (handheld competition does not offer) 
- Quicker programming than the competition (takes approx. 2 min.)
- OBD-II diagnostic software (includes live data monitoring of MPH, RPM, IAT, ECT, LTFT, STFT, O2 Voltage, Timing, KR detection, as well as many other sensors (competition does not offer)
- Revised Torque Management Settings for optimum performance
- Eliminates CAGS (Skip Shifting) on the 6-speed manual transmissions (GM)

Axle Ratio: Can adjust from a 2.xx up to a 6.xx in .01 increments. 
Cooling Fans: Will adjust both ON and OFF in 1 degree increments up/down. 
Power Enrichment (Fuel): Will adjust from -5% to +5% at WOT 
Spark (Timing): Will adjust from from -10% to +10% at WOT 
Shift Adaption (duration): Allows user to adjust the time delay during the gear change, i.e. quickness of the shift, from -25% up to +25% 
Shift Points (MPH): Allows user to adjust at what MPH the shift should take place, for each individual gear, in 1 mph increments. 
Shift Points (RPM): Allows user to adjust at what RPM the shift should take place, for each individual gear, in 10 rpm increments. 
Shift Pressure: Allows user to adjust the firmness of the shift action, for each individual gear, from -25% up to +25% 
Rev Limit: Allows user to adjust ON/OFF rev limits, for each individual gear, in 10 rpm increments. 
Wheel Sizing:
Actual Factory Wheel Size: Enter the factory tire size in XXX/XX-XX format, i.e. 275/40-17 Wheel Size: Enter the actual tire size in XXX/XX-XX format, i.e. 305/35-18 - The Predator then calculates the difference in overall height for proper speedo calibration
