I haven’t had the chance to put the newer fuel system in, the turbo pump is definitely more responsive and more power, as for mileage I’m running my first real tank at the moment so no data yet. I did max out the fuel screw before I put it on but it only moved 3 flats, may try some of Wes’s adjustments to get more power out of it. I am getting 14-15psi of boost out of this pump compared to about 10psi with the old pump.
