Hi. I'm not Sal but exactly 2 months ago I tested the Pro-M meter on the Dyno and at the track that same evening. My advise is that if you are running a chip, that you review the flow data from the meter with your calibrator. You just might have better results than without doing so. I gave my result to both Bob and Jim. I will be running a test again (changed some variables) and again will share with Bob and Jim. I used a Superchip and shared results with them too.

Hey FRDPLAY, Sal here. I don't want to say that you should get rid of the Pro-M in favor of my set up and the stock MAF. I'd rather you made the decision for yourself, based on how the Pro-M works for you. I can't say either way that one is better than the other, because it can have different results for different trucks. What I do know is that my set up makes similar power to the Pro-M meter/filter kit, costs less, and in my opinion, looks more factory. As far as the different meters go, Pro-M does make several different styles of meters, for all sorts of applications. Now you and BA Bolt both asked about the tuning. When we do custom tuning with mass air systems, there is a table called MAF Transfer Function. This is basically a flow vs voltage graph for the meter. If I were to make a mass air set up using a different meter than the PCM in the system uses, I must put the graph for that particular meter in the program. What Pro-M does with thier meters, is they modify the electronic part of the sensor so that you don't need a chip to use thier meter. The problem with this, is that the "recalibration" of the sensor is linear. Whatever they change, multiplies the voltage values proportionally through the rpm range. That is why many Mustang owners expeiriance problems such as high rpm ping, low rpm stumble, and so on, with Pro-M meters. When I do a system , I use Ford meters, with stock electronics, and them compensate the chip accordingly, because this is the proper way to do it. If I need a meter that will support high hp, I will have a Ford meter de-vaned, and then flowed, and insert those values. Hope this answers your questions

Sal, Got a question for ya? I'm going to test out this Pro-M meter at the track. You stated that your filter was creating similar numbers as the Pro-M. If this is the case, would it be better to change back to the factory meter with your filter kit or keep the Pro-M. I'm looking at possible "down the line" problems that might result from not having the stock calibrated meter on!

Second, i've seen a couple of these Pro-M meters and they seem to look different from each other. Is there a possible difference in the way they work based on their design?

 

Hey FRDPLAY,

I believe that if you try Sal's intake setup you won't be disappointed. I think Wyldman describes it best as the supercharger waker-upper! Not only does the blower spool much faster but it is alot louder especially at WOT. Definitely worth the $110 or so investment. .02 worth.
