The GT monitors and displays over fifteen different vehicle parameters (PIDs) on its 2.4" color screen. It also includes the all new Driving Coach feature which teaches end users to maximize their vehicles fuel economy potential. The GT performs vehicle diagnostics by reading and erasing diagnostic trouble codes; this level of vehicle transparency isn't offered by any OEM or by any other aftermarket product.

CUSTOM TUNING - The GT Platinum also supports custom tuning for Powerstroke's! But what is the difference between custom tuning and Bully Dog's preloaded tunes?

Bully Dog's pre-loaded tunes are designed for stock or lightly modified vehicles with modifications such as cold air kits, exhaust systems, or gear ratio changes. Unfortunately, as you build your vehicle with more complex modifications such as larger turbos, bigger injectors etc; the pre-loaded tunes are simply not designed to work with these heavier modifications and a "custom tune" is required.

Custom Tunes are created by one of Bully Dog / SCT's custom tuning dealers and are specifically designed for your vehicle and its modifications. Custom Tuning dealers have complete control of your vehicles PCM using the Derive Advantage Custom Tuning software and will optimize your vehicles performance for simple add-ons such as cold air kits or for high horsepower modifications such as turbo kits and larger injectors.

Owners of the 6.7L Ford PowerStroke's, the Bully Dog GT has proven to provide MASSIVE power gains, all while maintaining all of the factory emissions equipment.

Dyno numbers have shown an improvement of 128.5 horsepower and 217.8 ft-lbs of tq.

2013-2017 GT Unlock Cable: Previous to the release of this simple to use cable, you were required to remove your PCM from the truck and send it in for modification in order to allow you to tune your Cummins, obviously leading to down time for your truck. This simple cable allows you to use a Bully Dog GT (PN: 40420) to tune your, and any other 2013-2016 Cummins that also has a GT Tuner. This is a one time use cable, thus once you've originally installed the tuner using the cable, your truck is now permanently unlocked, even if you are to return it to stock, so you can tune your buddy's truck or anyone else's (as long as they have their own GT Tuner).

THE PROCESS:
  • Purchase a GT Diesel Tuner and the Cummins Unlock Cable
  • Install the GT Diesel Tuner and follow on-screen instructions
  • Install the Unlock Cable and follow on-screen instructions on the GT
  • Install Tuning from the GT Tuner

Great product. Simple install. Noticeable power and performance. I like the defueling, comes in handy here in Texas when it's blasted hot out and your running the heck out of the truck.

Sucks this is the only way we can unlock a Cummins ECM
I bought this with the intention to use for unlocking and keep as a digital gauge once I delete and tune the truck. I had a Edge CTS only as a monitor for my old Dmax and absolutely loved it... this thing is so small I can barely read the gauge ID's while driving. The ""graph"" is pointless and wastes half the screen. I was told that the bully dog units could disable my TPMS system since they fail to communicate with the valve stem in my aftermarket rims...it doesn't. At this point I would take DPP up on their unlock service of sending a used unit with the EFILive, or whatever tuner u go with, and have the option to return it. With the money difference b/t the Egde CTS2 and this doorstop... you may save money. Completely non-expandable also... trash!

Great Product
I keep the Bully Dog on my truck at all times. Never had a problem with it, and being able to change the mode with the touch of a button is awesome. Easy to install and use. Have recommended to several people.

I have a 2016 GMC Sierra 2500 Denali HD coming at the end of the month, Will this product suit it? also will it work for offroad / race applications when Ad-blue is deleted???

Yes, this tuner will work on that truck, however this will not support off-road/race exhaust.

Hey just bought a 2014 6.7 cummins. I was told adding a programmer to a stock truck with def, def, and egr would cause issues with higher exhaust temps, making the dpf filter fill up faster. Should i worry about that or will this unit work fine on a fully stock ram? just looking for better throttle response.?

In some cases we have seen more often regen cycles and higher temps on the more aggressive tunes with emissions intact. Add more fuel and unfortunately it is the nature of the beast to regen more. The bully dog is a rather safe tuner to use I don't forsee any issues for you.

Can I use the Stage 4 Performance and Economy Booster Package with the Bully Dog GT Platinum Diesel Tuner 40420? And will that bully dog package let me change the size of my tires from stock to 37""? I see that you have a combo package with all of the above but only for 2013-2016. My dodge is a 2012 3500 Dually. I also wanted to know if I purchase the stage 4 can I purchase a separate muffler just incase it's a little too loud? David?

Yes you could use a Bully Dog GT for that but not to add horsepower. We include the GT in the 2013-2016 packages because it is required to unlock the ECM so one can use the EFI to tune. Yes you can purchase a separate muffler to install in that exhaust. Should be able to remove the pipe right before the over the axle section and install the muffler there.

will this leave any files on the stock pcm so if I take it out before I go in for warranty work they wont know I have had it hooked up?

This device is not undetectable by the dealer as per it flashes the ECM. If would be an item that I would remove prior to going to the dealer. In most cases if you remove the tuner before going in, they will not necessarily know that it was installed. It is a very safe programmer to use.

If i buy the GT for my 2012 6.7 Powerstroke will i need to change my emission system? If I don't will it mess with my DPM at all in the long run? What i want to do is put a tuner on a stock pickup.?

That tuner is an emissions intact tuner that will go on a 100% stock truck.

Does it improve your MPG on a GMC LML? (not interested in HP gains but MPG improvements)?

You certainly can. They do not guarantee fuel economy but this will get the truck to a point where if drove efficiently you can see fuel economy gains.
