Optimize the  performance of your LS1 in minutes!

Easy push-button, hand-held programming.
These PowerMax Performance Power Tuners from Crane are loaded with features! These programmers deliver up to 30 hp and 35 ft.-lbs. of rear wheel torque increase over stock. They are calibrated to your specific vehicle; this allows you to recalibrate for taller or shorter tires, or a higher or lower rear axle ratio, and match the speed limiter to the speed rating of your tires. Other features include over 30 different tuning parameters for stock engines (including most trucks), and tuning for three Crane PowerMax Truck Power cam profiles. You can also tune your stock cam with four custom tuning modes: Stock, fuel economy, RV/towing, and high performance. With these PowerMax Performance Power Tuners, idle speed can be adjusted at 50-rpm increments, and shift points can be adjusted for stock cams and optimized for PowerMax Truck Power cams. They're calibrated for all truck auto transmissions, including Allison 5-speed. They also let you fine-tune your spark advance curve +/-10 percent from the Power Tuner programmed curve that you select, and they can be adjusted to your grade of fuel with auto adjustment, if low-grade fuel is accidentally used in high-octane mode. Performance settings can be infinitely changed, and you can easily return to stock anytime you choose. One more bonus is that they read diagnostic trouble codes! Installation is easy, the price is right, and the possibilities are endless!
