Answer 1

question is there a mass air flow sensor on the new air upgrade. .if u didn't. hook it back up or did and more flow of air is passing through it it will tell the computer that more air is coming in and make fuel pressure change ..its a stock car stock settings you might have to have some shop flash the computer to tuneit in ..
