New Gears.... now what???
I posted another thread on swapping my 3.23 gears for 4.10 on my RWD 2005 GMC Sierra 1500 with the 5.3L and 4 speed auto (4L60e). I took the truck in this morning and picked it up about 2 hours ago...

...I added a cold air intake (CAI) and a cat-back system (dual exhaust) with 40 series Flowmaster mufflers a year ago. Regardless, a custom tune will improve a brand new, factory fresh vehicle over the "canned" tune (one size fits all). Better throttle response, better MPG, better fuel management, crisper shifts, more HP, more torque and a long list of non-performance related items that annoy some people.
Now you add more info that you did not offer before. You have started on the right path but aren't there yet. Did you notice that I said you must add increased air flow for a tune to really be beneficial?
Add to the other things you have done, performance intake, injection, headers and maybe even a turbo, then you are ready to get real benefit from a tune.
Posting quotes from a website that is trying to sell a product is hardly unbiased opinion. I have no dog in the fight, spend the money if you wish, then provide us the before and after dyno results.
You do have the dyno results proving that the CAI and Cat-back improved drive-ability and power on your vehicle? Lets see them.

...Do you drive a beemer? I did too at one time but it still broke down like all the rest...
If you truly owned a BMW car, you should already know that aficionados refer to the cars as Bimmers and the motorcycles as Beemers.
