Actually, the computer still thinks you have 19lb injectors, with is normal. The reason for matching the mass-air meter to the injectors is to trick the computer. The mass-air basically tells the computer that its getting a lot less air, making the computer tell the injectors to decrease their pulse width (amount of time the injector is open). Even at the decreased pulse width, the 24lb injectors will shoot close to the same amount of fuel as your stockers, which makes it run correctly at idle and part throttle. This ends up being able to provide more fuel at WOT.
The problem is, its just a guess. Hoping that your mass-air will send the computer information that will allow the injectors to send exactly the right amount of fuel just doesn't work well compared to a custom chip & a little dyno time.
Dont get me wrong, a larger than stock mass-air is definately a plus
Just saying that after you install a mass-air and injectors, you should head out to a dyno and have them tune it with a wideband.
Good luck
