The Dinan Advantage

Dinan performance engine chips optimize fuel economy and emissions at light loads and as load increases the program gradually changes focus towards power. At wide open throttle the chips are dyno tuned for maximum power gains. Dinan chips increase fuel economy and power by optimizing fuel and ignition curves for supreme fuel. The chip also eliminates the top speed governor, providing top speed in excess of 170 mph.
