Hypertech ThermoMaster Computer Chips Eaton Posi Performance Differentials The DF175810's Dual Friction compoundThe Hypertech ThermoMaster Computer Chips (ref 5762) is a classic ECM performance upgrade from Hypertech that replaces your vehicle's stock calibration EPROM with a professionally tuned chip. For selected GM, Ford, and Dodge vehicles from the 1990s and early 2000s, the ThermoMaster optimizes air fuel ratios, ignition timing, and rev limiters for real world power gains. It's the original plug in performance chip no wires, no modules, no guesswork.
