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.

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...

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.
