My tune doesn't pull power, data logging shows it doesn't. At the end of the day, the 10R60 will handle whatever is thrown at it by a 2.7, tuned or otherwise. It is superior in it's shift quality compared to a 10R80 in our trucks, it's lighter and returns better fuel economy. The 2.7 Ranger I drove was decidedly smoother than the garbage 10R80 that my Tremor came with.Ford rates the 10R60 for about 450 ft/lbs tq and the 10R80 for about 600 ft/lb tq. While your tune does exceed this, all it would mean is faster wear and tear, as it is just on the other side of the rating. Additionally, I would not be surprised if your tune is programmed to help protect the powertrain by pulling power at times, so you are not having to replace the transmission every year. Ford/GM have power ratings on these ten speeds for a reason, and while they might be on the conservative side, it is still worth pointing out for someone who may or may not want to install a tune on their vehicle or other performance mods.
At the end of the day, the 10R60 can handle the 2.7 in factory form according to the specs laid out by Ford, but the 10R80 is a better match, especially for individuals who want to do performance mods and/or tow more. This is just my thoughts on this, though, which is what OP asked for.
The 2.3, nor the 2.7 are taxing the 10R60, you made a few anecdotal generalized statements about engine and trans reliability, when the OP asked " Aside from spending more money, is there a downside to the 2.7? "
So to answer THAT question, my thoughts on that are no, there is no downside. Buy an extended warranty and drive it for years with no worries. If an extra set of spark plugs over the course of 100k miles is a bridge too far,well its not the truck for you. The reason I'm not driving a 2.7 Ranger, is the God awful front end, it looks like a swollen Maverick.
