Raise Your Top Speed Limiter To Match The Speed Rating Of Your Tires!

When you feel the need for speed, Hypertech’s advanced Power Programmer III lets you electronically adjust your vehicle’s top speed limiter to match the speed rating of factory-approved high-performance tires. The maximum speed of many modern vehicles is governed by the onboard computer. The stock computer is programmed to shut down the engine when the vehicle exceeds the speed rating of the original equipment tires. But if you have installed tires with a higher speed rating for off-highway competition in sanctioned events, your vehicle may be able to achieve a faster top speed. A tire’s maximum safe speed under perfect conditions is marked on its sidewall. The codes for popular high-performance tires are: T = 118 mph, U = 124 mph, H = 130 mph, V = 149 mph, Z = 149+ mph.

The Power Programmer III gives you the power to adjust the computer’s top speed limiter to match these speed ratings (depending on application). Hypertech urges you to drive responsibly and obey all posted speed limits when driving on public highways.
