My Vehicle isn’t Listed under Change Vehicle
Q.
Why isn’t my vehicle included in the list under the Change Vehicle option?
A.
Chevrolet owners should choose the GMC option that matches the year of their vehicle. If your vehicle is very new or very old, it
may not be supported yet.
What Kind of Increased Performance Can I Expect?
Q.
How much extra horsepower will my vehicle get? What can I expect for fuel efficiency improvements?
A.
See page 2 for information about additional horsepower. Many people do find that the increased horse power helps them
get the most mileage out of their fuel as possible. However, since fuel efficiency varies so much between different vehicles and
drivers, there is no way to accurately predict fuel mileage increases. To get the best gas mileage possible, make sure to calibrate
and use the Driving Coach to improve your driving habits. See pages 12-14 for more information about the Driving Coach.
Note: If the Recovery process completes successfully, your truck is returned to stock. You will not need to do another step to uninstall the tune or return the
truck to stock. If the Show Setting screen still shows Recovery next to Download, contact technical support to have the unit reset
(there will not be a charge to reset from Recovery Mode).
