I have a friend who has a built evolution and he was telling me that there is a way you can eliminate the Mass Air Flow Sensor and your car will run just fine. I wanted to know if there is any truth to that and if so how could I eliminate it. He says he has a couple of friends that has done this and they gain more hp without it. Also that a few of them that have eliminated the Mass Air Flow Sensor have now had some problems with there cars.
