2016 challenger 4.5 whipple 4.75" pulley, car was previously tuned correctly making mid 700 at the wheel. the only thing done was a direct swap of the stock blower for the whipple. once on the dyno it would not go into PE fueling. just stays at lambda or 14.6afr even though the TB is logging fully open. also the bypass wont go above 3.5v it is staying open limiting boost to 10psi~ makes no sense... after a while it threw U1424 and P012b code.. but even with no codes it still wont go into PE fueling and close the bypass
i also tried a completely stock tune with only the injector data, still wouldnt go into PE or full boost... am i missing something simple or is there an actual problem with whipple and wiring. all sensors seem to be reading correctly....
