Has anyone out there used a tuner/programmer on their Duramax? I tow a Jayco 37'FW with my 2013 Sierra 2500HD Duramax it does a good job but I'm wondering about doing some performance enhancements. I'...

Shiner Bock you said a lot and I get your point.
But For me I don't need to have any driving fun, if the transmission is going to be my potential breaking point?
I'll keep my dead pedal and all of my parameters synced to the OEM specs. vs. new improved and fun to drive!
I having enough fun with the factory tune
That is just it. I don't find any of the factory tuning from any of the big three's trucks that fun and they need to rev to high to get power for what I am used to. As you can see on the dyno pulls bellow(this is with my stock turbo), I get stock power levels at much lower rpms which makes the power more usable for me and way more fun to drive. Imagine having the max horsepower and torque of the stock tune, but at much lower rpm and more to spare if needed.
The lowest line is the stock tune which ramps up slowly to keep PM in check. The other lines are the various different power levels of my tune and the lowest of the 4 is my "heavy tow tune" that gives me way more power and torque at a lot less rpm than stock does even though their peak numbers are not to far from each other. This makes a huge difference when towing.
I have not done any dyno's pulls with my new turbo and pulse manifold yet. It would probably be about 50-75 rwhp or so more than the max the stock turbo was able to do in the pic below. I will also mention that I put about 30-35k miles a year on my vehicles so having them drive like I want them to is important to me. Others may choose to spend their money on other things like motorcycles or luxurious RV's. I choose to spend them making my vehicles more fun to drive or better off road in the case of my Jeep.
