the Main Menu and follow the on-screen instructions.

The Power Level ratings listed may not be exact for your particular
vehicle. The listed ratings apply to the out-of-the-box tuning that H&S tuning
devices are shipped with. Any custom downloads may result in different rat-
ings and can be found at www.hsperformance.com/update-instructions.
speed limiter
This option allows for the adjustment of the factory speed
limiter. Most 6.7L Powerstroke trucks have a 98 MPH speed limiter from the factory. The
limiter can be adjusted from 55 MPH to 200 MPH. This option can only be changed during
the Install Download process.
Tire size calibration
This option allows for the re-calibration of the factory speedometer to adjust for non-stock
sized tires. For the most accurate speedometer reading when using non-stock sized tires, it
is best to measure the diameter of the tire using a tape measure rather than going by the
printed tire size. In addition, using a GPS is a great way to dial in your factory speedometer.
Entering a larger tire size will cause the factory speedometer to read higher while enter-
ing a smaller tire size will cause the factory speedometer to read lower. The tire size can be
adjusted from 31” to 34”
(this may change so be sure to visit www.hsperformance.com for product updates)
.
This option only takes a few seconds to change and can be adjusted at any time from the
Tire Size Calibration menu.
TPMs adjustability / Disable
Many 2011 - 2014 6.7L Powerstrokes are equipped with a TPMS or Tire Pressure Monitoring
System from the factory. This system is designed to alert the driver of a problem with the
vehicles tire pressures but is often a nagging inconvenience for those individuals wanting to
run lower pressures or get rid of the TPMS sensors altogether.
