Heres what JR has to say about it: Necessity is the Mother of all invention. No truer words could describe the genesis of the Jackson Racing PowerCard with Digital Tuning Technology.

Stringent emissions standards, ultra fast ECU's, and deadhead fuel systems left previous tuning solutions in the dust. For 2 years Jackson Racing experimented with various methods of fuel management with little success.. The future of fuel management would come from the computer industry utilizing a super-fast microprocessor that could react in milliseconds.

JR's PowerCard incorporates the latest in microprocessor technology and features an industry first tuning solution that is self-diagnostic. PowerCard easily installs in between the factory ECU and the injectors. During idle, mild acceleration or cruise, your car reacts just as the manufacturer intended. Mash the throttle and PowerCard responds with added fuel in milliseconds. Coupled with instantaneous Supercharged boost, power is delivered as fast as your right foot can work the accelerator pedal. Smooth transition and seamless drivability in a completely emissions legal package are the result.

Installation couldn't be easier. A vacuum/boost hose and 6 wire connections are all that is required. PowerCard installs in about 20 minutes. In fact, PowerCard is so advanced it not only knows when something is wrong, it will tell you how to fix it!
