39 cars. 2 powerstrokes. 1 cummins. 1 tdi. Every single diesel I've done at a minimum an intake/exhaust to, and on all trucks I saw an improvement in mileage. With intake/exhaust my superduty was sitting at 21mpg city, my cummins around 20mpg city, my HD 18mpg city, and my tdi... well, it's a tdi....
