Pro-M Mass Air

TwiLighTBluEGT · 09-15-2002, 03:50 PM

Will a 75mm Pro-M mass air meter that is calibrated for 19lb injectors work well with a near stock stang? Or is it better to wait until I have done heads/cam, etc.

it will work well with a stock car but if you plan on alot of near future mods and an increase in injector size might be called for then i would wait until i had figured out exactly what you were going to do to the car then decide on the injector size and maf meter. or you could get a meter that comes with a few different flow tubes and then just change the flow tube as you increase injector size pro-m is calibrated through the electronics so you have to send it back to them to get it recalibrated.

It made a very small increase for me. I would not have replaced mine if it didn't crap out on me. Aftermarket units are cheaper than stpock replacement units.

Wait till you know your new combo, so you'll know the injector size.
I used an 80mm for my S-trim with 30#'s, then had it recalibrated (again) 3 years later for the 42#'s when I did the heads/cam/intake.

I say go for it. I did a MAF conversion with a 75MM pro-m on a linclon mark VII (5.0 HO speed density) and noticed a nice increase in performance.

The stock MAF meter is your first restriction and a good place to start. You really dont need 24 lb. injectors until you are making over 300 HP.
