Performance Testing
This feature offers drag racers the ability to complete the 1/4 Mile and 0-100 KPH performance tests.
You can also download saved tests from your GT to your computer and analyze it using the Bully Dog Performance Testing Software. The software
is available by free download from
www.bullydog.com . See page 41 for more information about the Performance Testing Software.
There are two different styles available for both tests. The GT will show different test screens based on the style of test that is currently
selected in the Performance Testing Setup Menu.
Speed Sensitive Performance Test
Once this test is begun, the GT will show instructions to the user to first bring the vehicle to a stop. Once the vehicle is at zero miles per hour, the test is
ready. The test will automatically start once the vehicle begins to move.
Race Tree Performance Test
Before initiating the Race Tree style performance test it is important that the vehicle should already be at a complete stop. Once the test is begun, the
GT will display a classic race tree on the screen. As soon as the lights on the tree turn green, the GT will begin to record the vehicle’s time. In this style of
test, the GT will not wait for the vehicle to start moving before it starts recording performance data.
1/4 Mile Performance Test
This option will test the vehicle’s performance until the vehicle has
traveled 1/4 mile.

0-100 KPH Test.
This option will test the vehicle’s performance until the vehicle has
reached a speed of 100 kilometers per hour, which is about the same
speed as 62 miles per hour.
DPF Burn-Off
Also known as Mobile Desoot, this option is not available for all vehicles. See page 17 for more information about this special function.
Special Functions
These options vary from vehicle to vehicle. See page 17 for more information.
Diagnostics
This option reads the Diagnostic Trouble Codes (DTCs) from your vehicle engine. You can also erase these codes from here.
To look up the DTC codes, the following website is very helpful:
http://engine-codes.com/
You can also search for more information about DTC codes online using your favorite search engine.
SPECIAL NOTE: Street racing is illegal and extremely unsafe. The performance testing feature should only be used on a sanctioned 1/4 mile drag racing track.
IMPORTANT NOTE: Most DTCs indicate a problem with the engine, not with
the tune or the tuner itself. If you want to know if a DTC is being caused
by the GT or not, uninstall the tune and drive your vehicle for about one
week. If the DTC comes back, there is a problem with the vehicle and you
should take it to a trusted mechanic. If the DTC doesn’t come back, reinstall
the tune and test drive for another week – if the DTC comes back while the
tune is reinstalled, contact technical support. Be sure to have your tuner,
vehicle, and a computer with internet access available when contacting
technical support. See page 49 for more information about contacting
technical support.
