And the bike will certainly run noticeably cooler in my experience without the complications of a tuning system. An oil cooler really doesn't do much if anything for rider comfort, is more helpful cooling the engine when stuck in traffic, or cruising in 100+ degree weather.

As far as the right tuner for you, if you want to get more sophisticated, there are dozens of opinions here and over on the EFI forums. Do yourself a favor and make sure you consider the TTS tuning kit, if available for your bike. You get a bunch of diagnostic tools and can retain closed loop if you desire and effectively adjust AFR and timing for cool running without the need of a bunch of add on modules.

I'm not really too concerned about rider comfort, when talking about engine heat. Of all the bikes I've owned over the years, only two have been liquid cooled, and the ACE Tourer I had gave off more heat than my Dyna.
I just want to cool down the engine, which I'm sure will certainly extend the life of the engine.

Actually stage 1 tends to raise the temperature not lower it. Replacing the air filter and pipes gets more free flowing air to the engine which makes it run hotter. The reason you have to reprogram the fuel management is to get more fuel in to cool the engine down to compensate for the added heat you get from replacing air intake and pipes.

Which is why a real tuner (PC, TTS, Thundermax) is better. The primary effect of adding fuel is to make more power, and by doing so that extra fuel will result in cooler running. Motors that are too lean can tend to have decel pop and backfire problems when you change pipes and intake.
