Is it true this FPR cannot lower your base fuel pressure?

 

i know the aem one does but the b-m i think can only raise it

 

What do you mean by base fuel pressure? The B&M has a smaller window of adjustability than the AEM. If you find that you can't lower your fuel pressure enough with the B&M then you might have to modify it a little...here is some more information http://www.theoldone.com/articles/regulator/

 

Yes i was aware of that article. I wanted to confirm my thoughts. Thanks for the link and the help.
