Tracy and all,

I have an auto stock fuel pressure regulator which has seemed to funtion properly, but I am not satisfied with performance, i.e., inconsistent and proper mixture control. 

1. Would a MAP compensated fuel pressure regulator be a benefit?

2. Depends on the answers I get...:-)

There are too many possible reasons for inconsistent mixture to say that the reason is an uncompensated fuel pressure regulator but the system was designed with this type in mind. 

 

But what do you mean by "auto stock" ?  The stock Mazda regulator is manifold pressure compensated.  Is yours a three port regulator with a connection to the manifold?

 I've lost count of the number of builders that had this problem due to not connecting the manifold pressure sensor, wrong pressure regulator, no pressure regulator, primary injectors too large,  regulator set too high, not using a MAP compensated fuel pressure regulator, (list is endless, or so it seems).
