Hi Logan, happy to help you! This Bully Dog GT Platinum Diesel (Part # 40420) pre-loaded tunes are designed for stock or lightly modified vehicles with modifications such as cold air kits, exhaust systems or gear ratio changes. The pre-loaded tunes are simply not designed to work with these heavier modifications and a custom tune is required. For more information, please copy and paste this user's manual link.

Does it show the transmission temperature on a 04 Cummins with a 5.9

Hi Allen, I'm glad to help you! We can only look up by the vehicle. Since you didn't mention the specific vehicle, it's hard to tell for sure. To give you the correct information I would need the exact sub-model or VIN number of the vehicle.
Can I use it to do a egr delete and dpf delete
Verified Reply - Solomon
No, Kenneth, this Bully Dog GT Platinum Diesel Tuner (Part # 40420) does not offer a DPF/EGR delete function.
Does this do egr / throttle delete
