increasing fuel pump voltage

[lotta hp]

Does anyone run a KB boost-a-pump or JMS power max?

During WOT my voltage seems to drop to 13.3-13.6. Now lets say I run my walbro 450 at 15volts with the BAP wont my afr be more consistent and lower injector duty?

There was a discussion somewhere on here about running one. Obviously you'll have much more stable AFR's and be able to hold fuel pressure much easier. Can't remember the cons to running it though.

Only if your fuel pressure is dropping now.
