I thought i could run it off of the o2 since the stock computer is 19lbs injector and the o2 will only pull out about 20% of fuel out i thought it should still run rich but i guess i was wrong still lean. Then i put a stock maf on and stuck a 1/4 socket in the opening restricting the amount of air the maf would read and got it running somewhat ok.
