    5 Top Rated Questions

    I have a 2015 V6 3.7 Mustang with a Procharger installed. Two questions: Will this enhance the system I installed and give more power and do I need to re-tune my Mustang after install?

    • The JMS PowerMAX V2 FuelMAX Fuel Pump Voltage Booster would be an ideal option to run in conjunction with your new supercharger to increase the voltage of your fuel pump. More fuel equals more power. This item is plug and play.

    Will this unit work in conjuction with the JMS pedalmax and what would be the best setting for my 3.6 pulleys paxton novi 2200sl setup?

    • The JMS FuelMAX can work in conjunction with the Pedalmax without any issues. We would not be able to recommend a setting as there are too many variables in setups. We would recommend starting at 2.5 for 1/2 throttle trigger on the first dial, and around 20% on the voltage increase on the right dial, and adjusting as needed. The percentage needed as well as the trigger point will vary based on your specific car and fuel requirements.

    Would this be any help with just bolt on mods and JMS throttle booster and a tune in order to keep better fuel flow. I find my self trying to adjust the tune because it seems not receive fuel consistently. I have C L intake, open exhaust, JMS throttle booster, Boostmax, and a Unleashed tune.

    • The JMS PowerMAX V2 FuelMAX Fuel Pump Voltage Booster is used to increase fuel flow from the OEM fuel pump, and would not provide any benefit on lightly modified vehicles, and will only benefit vehicles that have exceeded the limitations of their stock pump.

    Does this work in conjunction with nitrous?

    • The JMS FuelMAX - Fuel Pump Voltage Booster V2 can be used with nitrous.

    Is this adjustable? If so would it be possible to run it with a stock motor maybe just with an intake?

    • This JMS FuelMAX Fuel Pump Voltage Booster is adjustable. The stock fuel pump is sufficient to work with an intake on your vehicle, so this would not be a required upgrade for an intake.

      It increased my fuel flow.

      My car was running out of fuel at the top of 3 rd and 4th gear. I installed this booster and it fixed the problem. It took me about 2 hours to install. The installation video was most helpful. I know it fixed my problem but it would not be necessary on a stock or slightly modified car.

      This saddle pump is just what the doctor ordered when it comes time with your new supercharger to keep the fuel coming for those new Roush injectors. You need the constant fuel pressure ,leave it to American Muscle to match this JMS fuel pump to keep fuel on constant demand

      Works amazing with my hellion TwinTurbo kit

      Love it and helps fuel flow. It only took four hours to put in and I have little technical experience so it really isn't that hard to install if you know what you're doing.
