JMS, MSD, or no fuel pump voltage booster

[DougS550]

When I got my whipple kit I got an MSD fuel pump voltage booster with it. I'm not a big fan of fuel pump voltage boosters so I installed a DW400 and called it a day. After reading about some of the fueling issues others are having I'm revisiting my decision. I haven't pulled logs but based on what others are experiencing I wouldn't be surprised if my combination is suffering from flow rate decay at high loads and would rather be safe than sorry.

After doing some searching I see most people are using JMS boosters. I don't see many people using MSD products and Whipple no longer offers the MSD booster on their website. Does it make sense to install the MSD I have or get a JMS. I have no interest in installing a return style system as this will always be a low boost, pump gas combination. If there's a proven reliable product out there I'll buy it.

Setup is a stage 2 gen 3 Whipple on a gen 2 engine with Kooks 1-7/8" long tubes. 91 octane, 3.750 upper, stock diameter lower, and factory whipple calibration.

Thanks for the recommendations.

I just installed whipple stage 2 with 3.75 puley, a DW40pulley, pump on my 19 with ID1050 injectors, on 93 and boostane. Wengerd easily tuned without issues. No BAP

Here's the short version:

This is the max voltage it will send to the pump. Stock is 12 ot 12.5. This will also prevent BAPs from using their full potential.

This is the max system voltage:

This is the command voltage at "high fuel flow":

These should be modified as you see fit with your own thresholds to get the behavior you want:

As always, it should be logged to make sure it's doing as intended. Some tuners run 15.2 volts all the time, which I believe shortens battery life. I haven't found a reason yet not to change this to where it only increases voltage during high fuel demand situations.

Thank you for the detailed guidance.
