Adjustable FPR question
When I bought my car (87 951), someone had already installed an adjustable FPR - like this or this.
When I checked it with my Mityvac, it looses an inch of vacuum or a pound of boost every second. - Is this normal? I did not see any gas coming through the vacuum nipple.
Also, I noticed that there are several models of this FPR that look the same, is there any way I have one made for different ratios of pressure at Idle/0/boost pressures?
My car Idles rich, drives lean, and is bang on under boost
Thanks for any advice.
