Is this a HD or standard?

don't believe that was originally on a buick...if it will bolt up, I guess you can test it out to find out what it will do

Steve ~
That was installed on my 87 GN years ago by the dealer,  and I have been running it ever since without issue.  I was entertaining the idea of installing a HD one, but figured I would see if this was a HD one or just a standard one.

Okay, first time I saw one.  The dealer units were adjustable unlike the original factory units.  It is a standard unit.  Standard typically will put out about 12 psi minimum and about 20 max

The HD units will put out about 18 psi minimum

I've got a dealer replacement here and that's not one Steve. I've got several like that I bought off evilbay and never tried to check the pressure so they may be the same as stock but it's not a GM replacement.

So what the heck did the dealer install?  Probably a cheap replacement that is adjustable. 
Don't plan on running boost over 20 lbs, so would a new HD unit benefit me?
