On the mass air meter I would stay with the stock one. But if you want to spent your money and replace parts then go with the Pro-M meter. I have a Pro-M on my Lightning and when I put it on during Dyno testing I saw an increase of 9.5 HP over the stock meter. I have since done some tweaks to it and my Superchip and should see some more HP. But I have not been back on the Dyno. At an increase of 15 to 20 HP I think you will be getting your monies worth. No comment on any other type of meter.One point to remember is that the factory air meters keep getting better all the time and the Lightning meter is an example of that.
