I purchased a GT Bullydog Diesel tuner for my 2008 - 2500 Ram with 6.7 Cummins primarily to get better mileage around town and better mileage and performance while towing my travel trailer. I also add...

I own a 2004.5 Ram 5.9L Cummins. When I bought it a few months ago, it came with a Bully Dog GT Gauge Tuner on it. I can tell you that forums for Ram Cummins diesel trucks, that tuner has a terrible reputation and is not recommended at all so I'm getting rid of mine
I have spent quite a bit of time on the phone twice with the Bully Dog tech folks, who are assisting me to try to VIN unlock this tuner, as I want to remove it. To the company's credit, the Bully Dog tech people have been very helpful, but the bad news is that so far, they haven't been able to VIN unlock the tuner from my truck. If I can't VIN unlock it, I will have to take my truck to the Ram stealership and have them flash the ECM back to stock. Ugh!! Still hoping to get it VIN unlocked, but not successful as yet.
BTW, OP mentions the Bully Dog tuner gives gauge type digital read outs. That is correct, but mine does not produce one very important bit of data that I want when towing: TFT (transmission fluid temperature). The OBD2 port does supply that data, however, as I put in an Edge CTS Insight Monitor, which does give me TFT. After I somehow get this Bully Dog cleared off my ECM, I plan to buy a Smarty Jr, which is the universally recommended tuner on the Ram Cummins diesel forums for the 5.9L motor. And the EFI Live is the tuner most often recommended for the 6.7L.
