Well the idea is good
The only way to get more power from an engine is to add more air, plain and not so simple, lol.
What you should do is to install a vacuum gauge where you can see it in the cab
temp or permanent
Find a SAFE place where you can get to higher speed and open up to WOT(wide open throttle) for at least a few seconds, like 10 or more
What you want to see is 1.5 to 2" of vacuum in the intake, it means good air flow
Assuming no Boost has been added
Lower means valves are floating so no suction, higher means restricted air flow, could be MAF or throttle body or even air filter
You must have some suction or power is lost as no new fuel can flow into the cylinders
As you add parts to an engine you repeat the test, I think you will find stock MAFs can handle more air flow, and stock injectors as well
"Better in hock than stock", lol, but..........spend the money wisely
MAF only samples about 10% of the air coming in, computer uses that data to tell the WEIGHT of the incoming air, computer already knows the AMOUNT/VOLUME of the air, not too hard to calculate when you knows the displacement of the engine, RPM of engine and throttle position.
Air/fuel ratios are WEIGHT, for gasoline you have 14.7:1 ratio, so 14.7 POUNDS of air to 1 POUND of gasoline
Or 14.7grams of air to 1 gram of gasoline
So the weight of the air is the bigger deal which is why there is a MAF sensor and an air temp sensor(IAT)
Colder air weighs more, at higher altitude air is lighter, so a variable that needs to be addressed and needs to be acurate.
Changing the stock MAF to non-stock MAF requires you to tell computer the WEIGHT calibration for the new sensor
