It will stabilize the voltage to the pumps. It will provide a regulated 14V even in the "off boost" mode. That can help if you have a weak alternator or overall low sytem voltage as it will work down to 10 V.

The only reason I ask is if you are using the alternator as your source, log your system voltage in HPT and see that it is holding a steady voltage under heavy acceleration. I ran into this with my truck knowing I had enough injector and should have had enough pump and found that the alternator would drop out under hard acceleration and the voltage would drop to 10.9 V causing the pump output to drop dramaticly.
It is something to check but now I realize you are on 80's, i think that is your issue.
What rail pressure are you running?
