4g63t drinks WAY to much gas ne ideas?

[jasonlee]

i have a 2gen with a 6 bolt awd with a big 16g, 510cc injectors, and walbro pump.. the car drinks soo much gas its insane.... also it starts hard every morning but if its warmed up its ok

another thing that was changed was i did the emission stuff removal from the taboo speed web paige... basically removed fuel pressure solenoid,. waste gate solenoid, cruise control and about every other emissions related thing as this car will not be a daily driver

Do you have an AFPR to go with that pump? If not, you need one. Do you have a fuel controller to go with the 510cc injectors? If not, you need that too!

haha TRUE . if you have bigger injectors and bigger pump then you're most likely running rich. get an AFPR and SAFC to lean out the machine

thanks! i kinda thought that would be the answer... but i was hopin to hear cheaper ideas...

guess i know where my next paycheck is goin

or double check to make sure your fuel pump isn't leaking all over the place

get that fixed yet?

but yea the walbro is going to overrun the factory 2g at idle and at lower loads when the engine is not using as much fuel. and all around the 510's are going to be pumping extra fuel in the whole time. That and i think the coolant temp not being hooked up and causing the ecu to not read the o2 sensor all 3 of them together would add up. I think you could get by with just a AFPR that would fix your walbro over run problem and you could lower the base pressure lower than stock to help accodate for the 510's short term. long term you would want something to tune it with to so you gain gain the fuel pressure back with out running rich.

look at my setup... I get about 15 miles to the gallon, depending how I drive.
