Frequently Asked Questions
1. What is Code 325 on my 2011-2014 Duramax?
It means that there is one, or more of the nine part numbers from the truck that is newer than the software on the GT. Update unit to the latest software version for your device. If you are on the latest version, call tech support so they can get the required information to have your part number added into the release.
2. What is Code 111 on my Ford Gas vehicle?
This means that the software (part number) in the ECM is not recognized by the tuner. Could be an unsupported vehicle, or just that the tuner needs updated to the latest version. If you are on the latest version, call tech support so they can get the required information to have your part number added into the release.
3. What is Code 322 on my GM gas?
This means that the software (part number) in the ECM or TCM is not recognized by the tuner. Could be an unsupported vehicle, or just that the tuner needs updated to the latest version. If you are on the latest version, call tech support so they can get the required information to have your part number added into the release.
4. What is code 335 on my GM gas?
This means that the tuner was unable to unlock the PCM. Make sure Key is all the way on/run, without starting the engine. Some special edition vehicles such as the Rocky Ridge vehicles will get this code. Our tuners are not compatible with some of these special edition trucks.
5. What is Engine warm up mode on my GT Diesel?
This is a feature that is enabled out of the box. The truck will run in the “NO POWER” mode until the engine coolant reaches the set temperature. The default temp is set at 172 degrees F. To change this temperature, or turn it off, go to the Main menu->Vehicle Setup->Set Defuel levels->Start up coolant temp. This can be lowered as low as 150 degrees F. It can also be turned off by pressing Defuel Off. To save changes just hit Go Back.
6. Why are my ABS and Brake lights on after disabling the traction control?
This is normal on the newer Chrysler/Dodge/Jeep vehicles. These vehicles were not designed for these systems to be turned off completely, so when we completely disable the traction control, these lights will be on as long as the traction control is completely off. Once the traction control is enabled and the key is cycled the lights will be off again.
7. What is VIN mismatch?
The VIN or part number that the tuner is currently locked to, does not match the one that it is reading off the PCM. Tuner could be locked to another vehicle. If this is the case, most of our tuners can be reset over the phone for a Fee. Also could be that the PCM in the vehicle may have been flashed after the tune was installed, Thus erasing the Bully Dog tune off the ECM.
8. How much does it cost to reset a locked tuner?
Current tuners like the GT’s are $250 to reset, older, discontinued tuners like the PMT, and power pups are $150 to reset.
9. What is code 424 on my Nissan/Infinity vehicle?
This is a security error. Mostly caused by low, and/or fluctuating voltage at the ECM. If this happens, disconnect tuner, and hook a Battery charger up to the vehicles battery with 10+amps and retry the download.
10. Why does my 2011-2014 Duramax not have an Extreme power level?
We have found with our testing that the power levels that we consider “EXTREME” (100+hp) cause the truck to regen too frequently, setting off trouble codes. We are continually trying different things trying to better our products, so there may be an EXTREME option in the future.
11. How can I change the speed displayed on the GT to match my GPS?
First you will need to figure out how far off the speed is in percentage. Once you know what percentage it is off by you can go to Main menu->Vehicle settings/Vehicle setup->Adjust speed display. Once there you can adjust the speed displayed on the Device up, or down by whatever percentage it is off. To save, press Go Back.
12. How do I correct the MPG reading on the GT so it reads correctly?
First you need to figure out what percentage the MPG reading is off by. Then on the tuner go to Man Menu->Vehicle set up/settings->Adjust economy display. Then increase the percentage if the GT is reading lower mileage than you are getting. Decrease the percentage (go negative) if the GT is showing higher mileage than you are getting.
13. How do I tell if my GT is Locked or not?
Go to Main menu->Show Settings, then next to “Download”, or “Status” it will say “Installed” if it is currently locked to a vehicle, or it will say “Not Installed” if it is not locked.
14. Why does my GT not power on any more?
Most of the time it is a bad connection, or a blown fuse. If you have a test light or a volt meter, test the 2 amp fuse on the OBDII adapter plug to make sure there is power there, If there is, contact Tech Support for further troubleshooting. If not unplug the power wire barrel connector from the OBDII adapter and test the inside of the barrel for power. If there is, then the OBDII adapter will need replaced (part number: 40400-105). If there is no power inside the barrel connector, check the wire, and the connection at the fuse box.
15. Why won’t my Power Pup turn on when plugged into my truck?
Check the Cigarette/Cigar lighter fuse. This is what powers the OBDII port on the vehicle.
16. How do I tell what software version my GT is on?
Go to Main menu->Show Settings, and it will be next to SV, SW, or Software depending on the version. Example: 220.127.116.11.

24. Will the Docking Station (part number: 40384) work with my PMT?
No. Only the older PCH pyro setup will work on the PMT.
25. Do I need to pull fuses on my truck?
Only if it is a 99-03 7.3L Powerstroke, 99-06 GM gas, or 01-05 Duramax. All others do not need any fuses pulled unless otherwise specified.
26. What is code 358?
Some GM trucks are susceptible to this code. Some vehicles are more picky than others. This is an error code that means the high speed communication bus we program on is either noisy, or there is no communication between the ECM, and the tuner. To fix this, pull the required fuses for your GM vehicle. Also, any aftermarket electronic devices can impede the download and cause this error. Disconnect all aftermarket electronics if you are getting this code, Aftermarket stereos(disconnect and jumper harnesses from the factory harness), aftermarket trailer brake controllers, chargers plugged into the cig. Lighter outlets, Amplifiers, remote starts, alarms etc. Disconnect anything electronic that didn’t come stock on the vehicle. Low battery voltage is another thing that can cause this error. Make sure Battery voltage is at least 12.2 volts with the key in the run position. If it is not, connect a battery charger with 10+amps, or connect some jumper cables to a running vehicle.
