Super chargers + MAP

[Falb, John]

They are made by a number of manufactures. (Paxton, Vortec, Bell,
ect...) $ranges from <150 to >280 for the Super FMU by Vortec, this one
is fully adjustable and includes vacuum as well as boost control.
Availability is not a problem( Summit, Jegs, ect...) To really tune one
right fuel pressure gauge, boost gauge, and a wide band O2. But really
they are fairly strait forward and fairly foolproof.

I'd like to know more about these boost dependent fuel pressure
regulators
like, who is manufacturing these?   Cost?  Availability?  Tuning?
