From my understanding what happens with a 'tuned MAFS',
They take what the car had factory for injectors, 19#, and divide it by the new injector/MAFS combo, 42# ... 19/42.
The MAF Counts (Voltage) is then multiplied by 19/42 to correct the air flow readings of the MAFS. It is not an exact science and there is a good chance the car will run rich or lean hear and there. And I'm just guessing but, I'd bet the larger the jump the more inaccurate the result will be and the more need for an actual tune there will be.

Besides that you have no need at all for that large of an injector for a N/A application. At least not if you don't have the ability to tune for them properly.

Why are you trying to run that combo , just because there calibrted for each other does not mean they will work right

I would stay away from the pro maf stuff , there are better ways to tune now

Unless you have a pro racer package there will be no way for you do to any adjustments to make it work , your going to need a tune

Let me know if I can help
