[schiccc]

ordered one 2 month ago from proflow.com.filled out the order form to my mods and when i got it i put it on my car and my car will hardly run with it.it backfires bad when i try to get on it.called them up and they told me to send it back.they had it for 3 weeks and just tried to put it on my car and same thing. i called them and there telling me something is wrong with my car but i know there is not because i have a c&l 76 on there now and runs fine wtf!!!
anybody else have bad luck with pro m??

What size injectors is it calabrated for? That might cause a problem like that...

it says 24lb right on the top of the meter and that is what my car has.

I had the exact same problem. I sent it back for a refund and put a 76mm C&L on and it works fine.

You guys have had good luck with the C&L's, I have been thinking on buying a new air meter, I just haven't figured out which one to go with

I basically told C&L to piss off because they did not make an application for my 94-95. I have no intentions of going to C&L and don't like the prices of Pro -m but if they are sending out chitty meters for the high dollars they charge, I don't know wtf to do. I need a 24# meter soon for my conversion and it needs a flange not a bullet. Hard to find. Ford Racing has some but not very advertized. I'll dig deeper

It seems like people are split right down the middle on this- Pro-M versus C&L. Can't explain what your problem might be, but I would send it back and stick to what works for you (the C&L in this case). I've had a C&L for 2 seasons now and no complaints yet, have heard the same from Pro-M users. Seems like a coin flip, unfortunately.

the only reason i purchased the pro m is because they will burn it to your mods instead of the c&l that tricks the computer but if the pro m wont even let my car run and makes it backfire then ill just trick the computer with the c&l. dont think pro m will get it right the third time around.

Have you modified your air intake? I see C&L make a meter for your year car. Why do you need a flange style? Just curious.

Have you thought of a granatelli mass air? They calibrate it for you application also.
