Another thing to add (that should not bother me but does) because it starts 100% quicker/better than it did is the tmax does not use the automatic compression releases.
Might be a factor if you plan higher compression later.
That's more than a minor aside. Cylinder pressures can't be "tuned away." Easy starting helps. But pressure is pressure. T-Max doesn't use the releases not because with some engine configurations they're not a good idea it doesn't use them because.... well....

Honestly the Thundermax can do a fine job. So long as compression isn't too great in conjunction with ACRs and, all too commonly, so long as you've got a competent tuner at hand to get you started who is good with the Thundermax software. Short of those things, however, it's a crap shoot unless you're willing and able to spend quite a bit of time dialing it in to get you started.
I do have it on the old 2000 Road Glide, and was glad to have it as it was the best product out there to replace a failed Marelli system 250 miles from home one weekend. The base map as it was described in their library was a close match to my engine specs too. Except it really wasn't. Not that the bike ran bad. In fact I'm sure many would have declared victory after the install, thought it was good, and kept right on going. But the map left a lot on the table. No Thundermax tuner within any acceptable range so too the inordinate about of time necessary to really dial it in. Now the bike runs well and I have all the benefits of the onboard diagnostics the bike never would have had otherwise.
Not complaining about the product, per se. But it is often not nearly as easy as "bolt it on and ride." And for a time a couple years ago they had a real problem with aggressive maps causing significant and even damaging detonation. Since, along with the ACRs, they also don't use the ION sensor to handle detonation issues that can be a real problem also.
