is a 80mm to big i have trick flow intake and cold air induction and 70 mm throttle body gears pulleys and msd ingition and other bolt ons i already purchase it form ebay it said for 19 or 24 injectors what should i do i dont like c and l. did i just waste a hundred dollars
Start researching before you buy stuff or you'll waste tons of money.
The pro m sensor should be calibrated for either 19 or 24 lb injectors, not both. Mine has the calibration on the top engraved in the plastic. The most important thing is that it is calibrated for the size injectors you have. Secondly, don't make the mistake of putting a Pro M sensor on a C & L MAF tube because they aren't interchangeable.
Lastly, I'm no expert, but I'd say the 80mm MAF tube might be a little big for your combo. You might not make as much power as you would with a smaller one, but I'm not sure what else it would cause.
The 80mm should do fine, but as said above it can only be programed for one size injector only i'm sure that is your problem. find out what the proper size it needs or you may have wasted money on a product that is no longer made by a company that is no longer around. (was a great company)
If time is of the essence, try emailing them or even better calling them. Give the code on top of the MAF and they should be able to answer that for you.
With it being an MAF, I wouldn't say it would hurt your power. You don't need the flow now, but you could later. Good Luck with the outcome.
