1 Stars   Better hope it works!!

The product might be good, but I unfortunately can't say that.
Mine was either bad or would not work on my car. I tried everything to make it work. And drove it more than I should have or normally would.
My bad, as it was making my car way rich and melted my cats. Lesson learned.

The story...
When I contacted LMR, they were told by Pro-M rep, to have me call them.
1. No toll free number
2. After 6 tries, I finally got to talk to someone.
3. I was told that I needed to send it back and if it proved faulty, they would refund my money for shipping and testing it. $72 additional moneys that I needed to pay out. If it tested good, I would be out the money.

What kind of company, thinks they're product can't be bad ever?????

LMR to the rescue as always!!!
I talked to Tommy who was dealing with me through this whole mess, and asked if they could give me a refund. And sure enough, they did.

LMR has had my business for years.
Pro-M will not ever!!!!

4 Stars   Can't beat a Pro-M

Image uploaded by parker s. Pro-M always does the trick and is so much less restrictive over the OEM. I like the fact that you can send in your MAF meter to Pro-M and recalibrate it if you ever upgrade to larger injectors as opposed to buying a whole new MAF. The only thing that sucks is that the screen inside the MAF tore easily.

Yes, I would recommend this item to a friend!

My old maf was bad so this made a huge difference! Idles perfect with no off idle stumbles. I combined it with a 3.5" Anderson Power Pipe. Car pulls hard now!

Yes, I would recommend this item to a friend!

5 Stars   Awesome Product

I bought this Pro-M calibrated for 19lb injectors... I had some blow by that pulled from my PCV into my old intake and trashed the stock MAF sensor. Even after proper cleaning it did't seem to act right and caused a bad hesitation during heavy acceleration. So I installed Steedas oil separator (Item #ST-5553710) between the PCV and upper intake, the Pro-M and slapped in a BBK CAI (Item #BBK-1557) with it just to clean things up a bit from my pieced together original intake. Everything fit perfect and no more hesitation and increased throttle response!!

Yes, I would recommend this item to a friend!

About This Brand

Pro-M Racing was founded in 1989 by Bob Atwood, a Ford engineer who was instrumental in pioneering mass air technology. Pro-M quickly became the most respected name in the industry, offering the only real practical solution to the restrictive production mass air meters found in most of today's production Mustangs. We manufacture mass air meters in various sizes, shapes, and styles, as both direct bolt-in replacements, and in universal designs, to maximize your engine's horsepower potential, by allowing your engine to breathe to its fullest potential. Each mass air meter is individually calibrated specifically for you Mustang or Lighting application on one of our in-house flow benches specific to your particular application, and fuel injector size, eliminating the need for time consuming and expensive dyno tuning. Others make claims, but only Pro-M Racing possesses both the intellectual and physical properties necessary to calibrate your mass air meter to within two percent of what the OEM considers the perfect baseline.
