I'm considering a pro-m maf for my build.

B5 S4/ RS4

Here is the maf I’m considering for my build.

I will finish the car and run a stock hitatchi sensor in the 85mm housing I have now. I’m very interested to see if i can refine the car even more with a sensor that is supposed to have a much better resolution… I know some of you on here are looking at the same thing, so I figured we can have a spot to report back on the pro-m maf.
You get a 30 point cal sheet for your tuna and can specify for which housing size you would like it calibrated.

That would be an excellent choice Josh. I am excited to see how my slot style blow through works out on my project car, if it does I will most likely change out the lightning maf on my S4 to an 85mm pro-m

EYEspI, are you Mantis on AZ? And Josh, aren’t you tuning Mantis’ single turbo A6 with this sensor in blow-through config?

Anywho, I can’t comment on that maf in particular, but I’m running a slot-style MAF sensor (PMAS HPX) in pull-through conig, and I have no issues at idle.

I am tuning the mantis car with that maf setup to blowthrough.
I want to run mine draw through.
I’m gonna do this to see if it’s worth doing on something other than a 700+hp car.

#5

Pro-m is an excellent choice.

#6

Yup

#7

Werd.

I have a pro-m that is for sale… new in the package w/ pigtail… PM me if you’re interested I suppose…

Eventually I will put up a FS thread for everything that I will be selling.
