        3 Top Rated Questions

        2014 Roush stage 3 Aluminator do I need a revise on my tune to add this to my car?

        • You certainly should speak with your tuner before adding this Roush Fuel Pump Voltage Regulator, or any fuel components to a Mustang with a boosted application. how the fuel system functions in your boosted Mustang is entirely dependent on the tune.

        If I am doing a 150-200 shot of nitrous, can I add this, any difference? recommended? (yes I have forged internals) will I also need a new tune?

        • The Roush Fuel Pump Voltage Regulator can be added to a Mustang with forced induction and nitrous. However, it will not affect your nitrous setup, and will not require a retune.

        Needed for Nitrous? Do I need this if running a 150-200 shot of N2O on my 2011 GT?

        • no but I would limit my n2o to 150 in short shots without forged internals

            Works great

            Worked just as advertised. Easy straight forward installation. After I installed this I had my car I had it dynoed and checked to make sure I wasn't running lean. My fuel looked good though out all the test.

            Super easy install!

            I have to say after realizing my car was starving for fuel with a blower I needed a boost a pump. I've heard great things about this BAP and let me just tell you took me only 30 minutes taking my times and running the wire to hide them all and wow super impressed, highly recommended!

            So easy to install!

            I have to say, after getting a supercharger installed and realizing I needed this to keep my car from starving from fuel this was a much needed upgrade. Install was super straight forward and only took 30 minutes to do so. Every thing was plug and play which made this so much better then trying to cut all the wire and possibly messing this up. For the TVS blower guys this mounts right into the intake manifold with the provided fittings. This BAP will only come on when the car goes WOT so it doesn't prematurely kill off your fuel pump since its not running all the time. Great peace of mind!
