and displayed on the GT or WatchDog. An incorrect
interpretation based on this information can lead to vehicle
damage. Be sure to consider the following points when
choosing a place to install your pyrometer:
Horsepower Output

stock (100+ horsepower), it is strongly advised that both
pre-turbo and post-turbo pyrometers be installed. (Both
pyrometers should be installed within the recommended
distance from the turbocharger.)
Preferable Mounting Location
Pre-turbo mounting is generally recommended because it
provides the most accurate vehicle operating temperature.
Determining a Safe Range of Operation
Regardless of the location of your probe, the Pyrometer
Calibration Procedure on page 26 will help you determine a
safe range of temperatures for your vehicle so you can set up
automated warnings or defuel points (if available).
Installing a pyrometer can be dicult because the exhaust
system must be drilled and tapped. Bully Dog recommends
that you utilize professional assistance if you have not had
experience with drilling and tapping.
