Yes I used pro-m MAF for years , I even sold pro-m there first 3 inch MAF tubes , they sell 2 types Tim what one are you talking about the adjusted MAF for the injectors your running or the 3 inch MAF tube and the stock MAF electronics installed
The recalibrated MAF adjusted to the injector size is the same things basically as using the diablosport MAFia the hugh difference is if the recalibrated MAF goes out and you have to change it (it happened a lot with me) you cannot get an ecact calibration back and have to return your full fuel curve as where if you use the stock MAF electronics in the 3 inch MAF tube the stock MAF is spot on if you have to replace it
jgrove at 218HP and 8psi I would say with a 3 inch MAF tube your right at the 5 volt limit of the MAF just before running out of MAF
In the end what I look for is whats going to give the best driveability and over all performance , WOT is easy anyone can tune that and most any MAF or combination will work ,
When your finished tuning you want the MAF voltage / counts to be in the 4.5 to 4.8 voltage range this helps to have the idle voltage / counts as well as cruise to be where they can give you the the best area for the best driveability
What I WILL NOT DO like some tuners do is let the MAF settings hit 5 volts and then go to the failed MAF tables to do your fueling for WOT , this in my opinion is not proper tuning but its done all the time
