Adjust fuelling from the output side of the ecu. This device will be able to cut injector duty cycle in half to run twice the size of your standard injectors. It will connect between the ecu and injectors. Limit map voltage to the ecu to 3Volts (0psi) and increase fuelling (tunable) upon detecting boost. Therefore it will have it's own map sensor. What they can also include in this device is a tunable boost retard funtion. These would sell like no other electronic device.

let me know what you guys think.
