Anyone recently used a Bully Dog?

Anyone used the Bully Dog GT tuner in the last handful of years? Seems like all the cases of someone owning one I can find were written a decade ago.

I have a 2008 Pathfinder LE 4x4 V6. I've done a K&N intake and had some exhaust work done to remove the secondary cats (replaced with 12" resonators) and put in the 14" 2in-1out Magnaflow muffler (thinking I'm gonna change to the 18" though). I recently had a bolt in a tire and used that as an excuse with the wife to get AT tires, and ended up buying 265/70/17s (about 2.5% oversize).

I usually fill up with premium. I'm mostly looking to get model-specific user experiences from a variety of situations, but I also have some goals. Wife and I are moving soon, and there's a good chance of towing a Uhaul in the near future, so having a towing tune I can switch in and out of seems nice. I'm looking for fuel economy gains as well, and I've noticed after all the work that I tend to be running a bit rich (after getting home and running at idle for a bit, my LTFT was around -10% and STFT was closer to -6%), so if the tunes will end up helping with that, that would be awesome. The Bully Dog seems pretty straight forward compared to a lot of other products I've looked at, but I'm open to some suggestions. I'm not looking to eek out every scrap of HP that I can, just make the rig better than it already is.
