Product Description
VMP Plug and Play Fuel Pump Voltage Booster 40AMP for 2011-2021 Mustang
From VMP:
We all know the proven benefits of a VMP Performance Fuel Pump Booster! Efficient, continuous 18v 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.
Fits 2011-2019 Mustang V6, GT, and Ecoboost
GT350 and GT500 require dual boosters
2005-2010 Mustangs use a different PnP harness, see recommended items
1999-2004 Mustangs require the use of a wire-in booster, see recommended items
Until now, Fuel Pump Boosters 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, see our recommended items below.
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 11-14 GT500, 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. On the 11-15 5.0L Mustang the factory single pump is modulated between high and low speeds by the computer. We recommend changing the high speed threshold in the tune (under Returnless fuel pump) from 0.80 lb/min to 3 lb/min (see below) on blower cars. On naturally aspirated cars this value can be raised to 4-5lb/min for NA tunes and lowered back down to 2-3lb/min on the nitrous tune. The same values would be recommended for cars running E85. The 2015-18 5.0L requires slight modification to connector.
