I went in today to get my leaky valve covers fixed and the mechanic says that my car is running lean. He said that he checked for vacumn leaks and the supercharger has none. He suggested that I change the MAF sensor because they were faulty and he says that he has seen them go bad alot. He said that there is a wire inside the sensor that easily gets clogged with debris. I was looking at upgrading the MAF sensor anyways so I wanted to see what everyone thought about the Pro-M 75mm Bullet MAFS on the Supercoupe Performance website. My plans right now are to put a BT motorsports CAI and evenutally put on the exhaust system. Thanks for any advice.
