It has already been said, if the dyno operator didn't hook up correctly who knows, it's worthless IMO. Just for your information, Dynojets are about the highest reading dyno's out there. The reason someone should use a Dynojet is because they've become the standard to compare your numbers against someone else's. Having said that, you need to do your dyno in 4th gear, with RPM (not MPH) & correction set to SAE / smoothing 0.
Agreed, get a Shark Injector.
Take your Bimmer somewhere else & get another Dynojet dyno.
