The TDN app is designed to help customers easily exchange vehicle tune files and log
files with an HP Tuners-authorized tuner, whether that tuner is just around the corner
or on the other side of the country.
NOTE: Unless you have a relationship with an authorized tuner, you cannot use
this software to tune your vehicle.
Before you begin, you will need to identify a tuner that is knowledgeable about the
tuning needs of your vehicle make and model and is willing to take you on as a
customer. Once you have selected a tuner, the tuner can advise you on any special
requirements of the vehicle to be tuned.
