NEW VMP PLUG N PLAY FUEL PUMP BOOSTER FOR 05-10 MUSTANG GT/V6 We all know the proven benefits of a VMP Tuning Fuel Pump Booster! Efficient, continuous 17v output (40A) designed to get the most performance from your stock or aftermarket pumps. It stabilizes voltage as well as increasing flow rate. Simply tossing a larger set of injectors into the system won't necessarily be the answer to your high performance fueling needs. Until now, Fuel Pump Boosters (or "Boost-A-Pumps(r)", a name owned by Kenne-Bell) have been seen as an "I'll get to it.....someday" proposition. Why? Because the average person doesn't have the experience nor confidence that they'll hook them up correctly. We heard you and we've solved the problem, making it uber-simple to install the performance headroom you need, doing it right the first time! Dual pump systems, like the GT500 should run twin units for redundancy and lower temps. Original "wire it yourself" boosters continue to be available. We recently had some questions about competing fuel pump boosters and how they compare to the VMP unit. The VMP unit is designed to be always on, it's a high efficiency unit and does not require any additional power wires or pressure switches. We do include a 30 amp fuse to replace the stock 20 amp fuse in the underhood fuse box. We hook ours up all the time to prevent any pressure spikes that may occur when a booster is triggered in the middle of a pull by a pressure switch. In the case of 05-10 Mustangs and other Fords that utilize a returnless fuel system, the computer is already modulating fuel pump duty cycle and only giving the car the pressure and flow it needs. For tuning, we recommending you reduce the Fuel Pump Voltage Table (under Returnless fuel pump) by 1-2 volts all over and fine tune from there by datalogging.
