Sorry Ron but Brians statement about the Bosch maf failures is correct, almost every Bosch maf that I've seen has failed with too high a signal.

I've seen hundreds of 75 and ZT diesels, I see them on an almost daily basis and sometimes multiples a day, I always check the maf voltage and airflow readings to see if they're in spec.
I don't do this to sell anything to anyone, all I want is for owners to get the best out of their cars, if their maf has failed they're free to get a replacement from anywhere they want.

I've also used a Synergy for years too, and know that using the mafam on a failing Bosch maf with too high a signal just throws the airflow readings even further out at both idle and higher up the rev range no matter what mafam setting.

In no way am I knocking the Synergy in any way, it's provided an effective simple way of boosting the performance on our cars and enabled the use of the cheaper Pierburg maf, but the Pierburg does underfuel at 3000 revs.
