Question about aftermarket MAF's

I have had great luck with Pro-m. I am tring to put on a granatelli now (3 months++) No support from tech, back order, wrong connector to factory harness... it never ends. Pro-m will give you accurate readings, they come with a flow sheet if you have a tuner of some sort. I wish I stayed with them but I wanted to try the granatelli because it is plastic and stays cooler. I may still go back to pro-m if I can't get my car running with the new one they are sending me in a few days.

I love my 80mm Pro-M. The car didn't at first but once she got used to it things worked out nicely.
