I know this has been beaten to death. However, I'm almost certain that my rewired 190 Walbro fuel pump is over running my fuel system. I usually fill up my tank when the fuel gauge line hits 1/4 of a tank. At this point, I usually have around 165 miles to the tank. I know I can get better gas mileage. Of course, I like to put the pedal to the floor a few times a week--like everyone:)I have a pocketlogger and at idle my o2 sensor checks out fine (.04v). And yes I believe it's stock. I have new plugs/wires, etc, etc, no boost leaks. I'm about to buy an adjustable FPR w/an in-cockpit fuel pressure gauge. Which is better? The charged air unit of the fullthrottlespeed one??? Any advice guys? Mods below.

Small 16G, MAS mods w/K&N, 3 inch rnr turboback exhaust, Arospeed muffler, MBC (18 psi), 2.5inch dejon upper i/c pipe, rewired 190 walbro, 3 inch dejon intake, pocketlogger
 
Fuel filter is one year old as well. And yes I've done the MCCC treatment:thumb:
