Here is a test to see what that Boost a Pump does or does not do.

Test 2 is same driver, same drive style and of course same weather as being done 2 hours after test 1.

This BAP has a adjuster knob that is scaled from 0 to 50.

Test 1 had knob set to 15 which is what WCC told customer.

Test 2 had knob set all the way to 50 which means pump voltage is at the highest

As results below show all that did was drop injector duty cycle to drop from 114% to 109

Average PE injector needed down by 4 lb/hr and max WOT injector down by 4 lb/hr.

In the end the Boost a Pump does crap and in fact I believe the design of the C6 fuel pump electronics protect the pump from higher voltage thus BAP upping voltage to fuel pump did what shop measured with a fuel gauge on fuel rail a whooping 2 PSI gain from 60 PSI to 62 thus there is no way the BAP could cause those 32 lb injectors being reduced from 110 % duty cycle to a proper 80% or less.
