Thank you for this.
I do have one question.
According to Duramax tuner (not that I trust them and the entire week of R&D they spent on their tune) their stage 3 tune Sport Economy Tune (+45HP / 60Ft-Lbs) is similar to yours. but they say
QUOTE:"A very fun tune that is reccomended for daily driving use in unloaded scenarios. This tune has a little bit too much mustard for extended high output pulls such as those you'd encounter while towing. "

will I encounter any issues towing with your tune?
I tow cross country and through the Rockies and I really don't want any engine or transmission problems while in the mountains.
Is there a reason they say you shouldn't tow with that much power?

The GDE tune is safe to tow with as the factories safeties are still active. The ecm will defuel the engine if coolant, oil or egt approach the factory limits. We know nothing of the duramaxtuner, but their tune most likely turns off the safeties if they do not recommend towing with it.
