Do you now have "ice-mode" and have to push madly for any effect?
If so then ABS action is probably "beating" the vac servo (which on a 370 is a bit different anyhow).
Cure? Maybe a big vac tank or a diesel vac pump (diesels have no manifold vac)
Just a thought, Fritz

A very interesting thought too! A temporary vacuum tank setup could be installed to test your very interesting theory. Let's hope some of the racers on the forum give it a try and post the results.
The more I think about it you could really be onto something. It's worth doing just to make sure that it ISN'T a lack of vacuum assist.
