Just got this brochure from Autobarn: Power Boost Valve -instant power for efi cars, goes on to state "...PBV has a higher air/fuel mix (1:1.7 instead of 1:1) meaning fuel pick up is quicker, resulting in faster acceleration...FSE PBV is fantastic for modified, high performance or turbo cars...providing additional power down low...eliminating flat spots and throtle hesitations...simply improve the fuel flow thru your injectors" has anyone heard or used such a device, it replaces the existing fuel pressure control valve, and just bolts on in its place....????
