I'm pretty sure that it should only work on boost and not while sitting still just revving the engine
Am i right?
If its clicking dose that mean its knackered?
Cheers for any info.
Depends on the boost strategy mate, some maps will pulse it at around 3000rpm at approx 2hz to smooth the boost climb on 4x4s. Some of my strategies are programmed this way.
