The Porsche Cayman S 3.4L has always been an excellent vehicle to do an ECU Flash on. Our partner in Spain, Rush Works, who manages www.vividracing.es recently did a flash on one of his customers cars. The Cayman S gains tremendous improvements through the powerband and most noticeable low end torque gains. With the ECU flash we are able to raise the rev limiter which also adds to stronger top end pull. This particular Cayman S made a nice 14 wheel horsepower on their dyno.
