RE: New MAF sensor???
ORIGINAL: vristang
The Pro-M method of "calibrating" to an injector size is to modify the voltage output of the mas sensor. This means that the voltage output of the mas will be different depending on what size injectors the mas was cal'd for.
There is no gaurantee that the voltage output of the Pro-M mas will be the same as the Ford mas.
If this works for your car it is purely by coincidence, and I do not recommend any one else expect to get the same results.
However, I think you will get better results by getting the correct mas.
If that doesn't make sense then read the post by luckythirteen again.
Your options are to get a new MAF tube with new MAS, or get a new MAS from Pro-M (Pmas is the new name?)

How is it not right if it's working better, seems every bit of right to me. It's just like using the stock MAF just a larger housing, what's wrong with that???

So if they're both calibrated for the same injectors I shouldn't use it and it's going to run like crap if anyone else does it. I compared them to each other and they're exactly the same just different brands. It's like using a borg warner part instead of a Motorcraft part. But for some reason it's working better. That's like saying that you're not allowed to use a different MAF than stock.

The voltage output of a Pro-M MAS will not match the voltage output of a Ford MAS. (They may be close, but they were not calibrated for the same application)
Unless you have put them on a flow bench and compared the voltage outputs for a given airflow (using the same MAF tube), you have no idea if this is correct or not.
You said yourself you can't run the car hard to find out.
There is an adaptive ability that the eec can work, most likely you have eaten all that up.
Your setup is not right, regardless of how the car runs.
