Upgrading power and performance on certain Ford vehicles requires something of a different approach because many Ford models do not have replaceable chips on their electronic control units. That's why Hypertech offers its Hypertech Performance Modules; these devices plug directly into your Ford's service port and override the factory settings in the electronic control unit. Hypertech offers two different types of Hypertech Performance Modules. The first is designed for Mustangs with nitrous and has two settings: one that adjusts for normal driving, and one that causes the engine to put out more power when you are actually using the nitrous boost. The other type of Hypertech Performance Module is designed for Ford trucks and SUVs and has three stages, each to get more horsepower and torque out of your engine at specific times. With the push of a button, you can get 50, 80 or 100 more horsepower from your engine on the fly. This comes in especially handy when towing or hauling heavy loads. These performance modules come with a switch that can be easily mounted on your dash. The modules can be plugged into your Ford's wiring harness, giving you immediately accessible power right at your fingertips.
