Wonder why this never happened?

During that long incubation period, TRD decided to design the supercharger kit with an electronic boost controller--basically an electronic actuator for the standard Eaton bypass valve, which works like a wastegate, dumping boost at two critical points: one, between shifts and two, when the ECU goes into rev-limiter mode. On the dyno chart, you can see the power drop almost by half from the loss of boost just before the rev limiter stops the dyno pull. In the future, TRD plans to develop its superchargers with fuel pressure gains by using intercoolers, differently sized pulleys and electronic engine management systems to up the boost levels.
