New GDE tune but...

Just got a new GDE tune for my EcoDiesel. I did the trans tune and engine tune and honestly it has been amazing to drive. Shifts great comes on boost perfectly, I actually removed my Banks pedal monster because it was already 1,000 times better.

I did notice though that I can smell my exhaust. I don't recall smelling it nearly this much if at all. I've always been able to identify the DEF smell but I can certainly smell a more pronounced diesel exhaust. Has anybody else had this experience?

It's not a deal breaker, and as long as it passes emissions I can certainly live with it. I was hoping to get some more information also on what all the tune tweaks. Has anybody's DEF consumption gone down? Not that I've had it get carried away (if anything I feel like it was barely using any at all)..
