This is the max WHP you can get where the MAF will give a correct reading. After that you are playing with fire as the MAF will not be able to read how much air is coming into it.

When your planning a build w/ injectors/MAF you usually design for capacity... i.e. the max power you will likely have and use it as a buffer. A MAF use air flow as a derivitive to add fuel. So the minimum would be when there is almost no air flowing through it aka close to idle. It uses that information to open the injector at a certain pulse to deliver the minimum fuel.

No they are not. They can go on anything once the ECU is programmed for it
