PIT Tuning achieves very impressive fuel savings by making changes to the PCM (the vehicles computer). Using specific air/fuel ratios and spark timing maps which have been carefully measured and tested on a dynamometer, your vehicle will be optimized for fuel efficiency. This has been shown to increase fuel economy by up to 5-6 miles per gallon on gasoline engines, and up to 11 miles per gallon on diesel applications.
PIT Tuning programs throughout the entire throttle range, offering maximum fuel savings for everyday driving. Hand held programmers generally only offer gains when the vehicle is at wide open throttle, or when the driver has the pedal to the metal.
