This range AFM delete does just as it says. Unfortunately I found out about it too late. My 09 Silverado had to have new Pistons and rings at 107k miles. Since I got it back from the dealership I haven't driven it without the range device. The truck runs good, that annoying vibration on highway driving is gone, and hopefully there will be no more oil consumption. I only checked one tank and I went from an avg if 15mpg to 14.6 I would recommend this product!
