Looking for the most powerful PCM-tuning tool on the market? Unlike typical off-the-shelf programmers, the DiabloSport II from SLP comes armed with an ultra-hot custom tune developed specifically by SLP for your Charger/Magnum/300C including 2008 SRT-8 Challenger.

SLP's performance-optimized PCM programmer with integrated scan tool is a dynamometer developed, adjustable tuning upgrade which provides a significant performance improvement that you'll really feel in both 5.7L and 6.1L engines.

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 powertrain functions for maximum power and drivability. Manipulate rev limiters; correct your speedometer for non-stock gear ratios and tire sizes; boost transmission line pressure for firmer, quicker shifts (automatic transmission only); remove the factory top-speed governor; and more-all in minutes and at the touch of a button.

Backed by our Two Year Warranty.
