Stage Notes

Stage 1 on the 3.0d 325d and 525d 194bhp engine provides exceptionally good power gains without any requirement for other modifications. The limitation on this engine are the injectors which don't allow enough fuel supply to provide power gains above stage 1. For those wanting more power and torque from this superb engine please see the stage 2 and its requirements.
