I have a LT1 with full LT4 fuel system. Im trying to figure how far I can go on E before running out of low side. With that, how far is a JMS BAP going to take me? A couple of shops I talked to claim no improvement from the JMS BAP (or very minimal) - note they were also trying to sell me an aux system instead.

Im not a huge fan of the DSX auxiliary pump, at that price point, I would rather just spend the money for a double/triple in-tank.

As of now, it's a basic build: whipple 3L with 4" SC pulley, headers, exhaust, CAI, LT4 fueling, and DSX FF sensor.
