Hi Guys, Long time reader, first time post! :o) I've been researching the 'Power Boost Valve' for my N/A, and I found the following information. (You can also purchase this product from Fensport) Firstly, this valve has an adjustable fuel pressure, effected by the movement of an adjustment screw on the crown of the unit. New Power Boost Valves are pre-set with a maximum fuel pressure of 2.5, 3.0 or 3.5 bar, depending on the vehicle in question, and similarly (to the original valve) the fuel pressure is reduced by 0.5 bar approximately at idle. There the similarities end. On acceleration from standstill the Power Boost Valve fuel pressure will increase at 1.7 times the standard rate. This will produce a healthy, strong fuel mixture strength which will instantly improve the drivability of your vehicle, providing:- instant throttle response removal of performance flat spots faster acceleration extra engine performance The regulator enhances engine performance on acceleration by enriching the mixture strength. On constant throttle and cruise conditions the valve returns to a normal regulator function. The Power Boost Valve is simple to install and in most instances basic fitting instructions are provided. These units are mechanical and are considered maintenance free
