How far did you guys go before losing MPG?

I get down to about half throttle where mpg starts taking a good hit.
But seriously, the only thing I ever did that really hurt mileage was going to bigger tires. Aggressive AFC mods are going to hurt mileage - smoke screw, loosening the starwheel. Black smoke is unburnt fuel. Bigger injectors certainly won't help.

i have bigger injectors, my starwheel is all the way down my fuel pin is ground. i still get 18 city and 20-22 highway, just depends on how bad i get in it my worst tank was16mpg, and that tank had a 4x4 drag race on it and a lot of abuse on the road that week(friend got new chip in his powerstroke and i could still keep up fairly well in the ole girl)

If you dont change your pump settings yes its the same amount of fuel,you have a 1st gen,you should know how the VE delivers its fuel.With larger holes Delivery is better.Even when it gets turned up,good nozzles will be more efficient therefore yielding better mpgs.Look at the vw tdi.With just a larger nozzle install you yield 3-5 mpg as well as power!

point is... the amount of fuel that you supply a set of injectors should be tuned to that specific injector. right amount of fuel will yield better atomization and efficiency; too little and efficiency will take a hit. you can MAX out a pump and the pump will only deliver X amount of fuel at X pedal position. easy on the pedal means easy on the fuel mileage. AFC tuning and fuel pin choice has ALOT to do with it all the same. i've actaully cut and ground mine to the point that i probably dont need the smoke screw at all; i'm at one full turn and its still abit much on take off at WOT

when you turn up a pump unless you REALLY change some physical parts you're working with a hunk of metal that has design limitations. you arent changing any physical characertistics of the internal parts of the pump (unless its a fuel pin) you're just taking some of the "designed flaws" out of the mix and allowing the pump to operate beyond the factory underpowered settings. so as stated before; before and after turning the full load screw your delivery rate will be the same, until of course you go past the rack travel that the factory settings had you limited at. THEN you'll be delivering more fuel than usual and hurting your economy

moral of the story is i talk alot , and economy is easily controlled through how heavy your foot is
