MAZDA 929 1990-1995 Performance Chip

Performance chips are car accessories that we hear an awful lot about, but which seem to be explained in slightly hazy, extremely confusing technical jargon and pseudo scientific babble. Terms and phrases such as torque, aerodynamics and the fuel ratio are used indiscriminately and it seems that you would need to have an engineer degree to understand what a performance chip does! At the risk of grossly over-simplifying things, a performance chip is intended to improve the actual performance of a car by ensuring that fuel is not wasted and that the correct amounts of fuel and force are available as they are required.
