Looking for the most powerful PCM-tuning tool on the market? Unlike typical off-the-shelf programmers, the 2005-06 GTO/2005 C6 Corvette/2006 Trailblazer SS DiabloSport II by SLP comes armed with ultra-hot custom tunes (replacing the Standard Diablo Performance Tune) developed specifically for your LS2 based engine, which includes the popular ZL435, ZL465 and ZL500 Corvette Performance Pacs, 421 and 455 GTO Bobcat PerformancePacs. Through extensive testing on our in-house dynamometer, our engineers were able to determine the precise levels of spark and fuel required to achieve optimal horsepower and torque at each rpm increment. As an added bonus, the ZL465, ZL500 and 455 Bobcat PerformancePac tune when loaded, automatically turns off the 02 sensor codes for Corvette's and GTO's equipped with long tube headers and high flow catalytic converters. Eliminating the annoying check engine light.

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 beyond the PerformancePacs. Each custom program has ignition timing and fuel is optimized for each package, allowing you to plug in the tune, download the tune, and more-all in minutes and at the touch of a button.

NOTE: If your vehicle is not equipped with all parts included in each PerformancePac, do not worry, the tunes will still provide industry leading power gains.
