fuel pressure regulator

[acg72]

im thinking of installing a msd regulator. they have a regular adjustable and one for turbos (moor boost more pressure). they are fairly inexpensive. any opinions if they are functional and compatable w/ TB's?... also installing a walbro pump. about what pressure should i run with all stock. or is there other combinations of things to do for it to run as it should. newbee and learning.... thanks

The regulator must be turbo Buick specific, can't just bolt a generic one on.
Here's what the Buick one should look like

As far as fp for a stock motor, fp should be in the 40-42# range with the vac line disconnected. Need a scan tool to see what the BLM's are at idle to determine if fp should go up/down and what O2s are at WOT as well.
