Default Correct voltage on KB boost a pump?

Does anyone know the correct voltage i should set my boost a pump at? I have the 40amp kit and i dont believe i saw my tuner set touch my boost a pump voltage. Im making 425rwp on a 3.625 whipple pulley and the voltage is set on 40. Any input would be great. Thanks!

i believe there are two possible settings
for the BAP:

1) Max voltage
2) Some voltage below Max.

if for whatever reason you don't like the idea of
running the BAP at the Max setting, you would
set it at a value that would result in a (chosen)
fuel pump duty cycle (ie. 95%) at your maximum
WOT rpm.


this is a good chance for us all to learn about the
BAP, maybe someone else will weigh in and give
more insight.

Yeh i know nothing about the settings of the pump. I have the GT500 pump but have not had the time to install it. Dont really need it yet so itll be sitting there for a while.

Voltage or amperage?
Your question leaves much to be desired in the comprehension dept.
I really doubt your pump is running at 40 volts...
40 amps, maybe, but not 40 volts.
Reread and restate the question again.
Are you setting amps or volts?
And whats a 'tuner set touch'

I would set it with the pressure desired at the widest injector pulse width.
Back to the tuner for more dyno pulls...

I leave mine on max all the time, at the pump its self you should be getting a reading of 17+ volts if I remember right.

Sorry i meant 40 amps. I just checked and im at 40 amps which is the max, so does that mean im maxing it?

When i said "tuner set touch" it was a mistake and was suppose to be "i dont think the tuner set/touch my boost a pump. Sorry for the confusion.

running it at max will give you 17.2 volts give or take, turning the **** all the way down will give you around 14 volts. just turn it all the way up. on mine i didnt even use the ****,i just spliced the 2 wires together to make it run on max all the time,no chances of anything ever happening to the **** to make it go down.
