The exciting new HPT series, towing program is the result of an extensive research, engineering and development effort. The mountains of Washington, Oregon, Idaho, Montana, Utah, and California were the proving ground, all playing host to countless, heavy-towing sessions designed to challenge this new programming.
The HPT series programming excels in towing heavy and uphill. This exciting new engine control programming is based on highly refined and totally unique fuel and start of injection timing curves. Engineered as a total-performance engine control program, the HPT delivers a crisp throttle response and exceptional tip-in power along with strong towing performance. All this with a cool, clear exhaust!
The new HPT series features an automatic transmission shift-schedule tailored to control engine speed within its peak torque output range for optimum towing performance. The engine and transmission are directed to function as a team to get you moving and keep you rolling --- even in the most difficult conditions. The HPT series is perfectly suited for the heaviest towing or hauling. With it, you can run hard, even up the steepest grades while maintaining an exhaust gas temperature that is safely below GM's prescribed limit. You will be amazed at the stark lack of exhaust smoke and those who are following you will be happy, too! At the same time when fuel costs are increasing, you will enjoy the best possible towing fuel-economy.
While the HPT is specifically designed to optimize towing performance, make no mistake about it; the HPT is no sissy tune-up. Your 6.5 will suprise the bullies.
