Agreed.  With your description of throttle and shift points, you should be doing much better than that.  On both my 2000 and 2001 ST, I've had much better gas mileage.  With stock tune, getting 50 mpg on the highway was not a stretch.  I even got 54 mpg once going steady state 72 mph on the highway.  But more realistically, at least 48 and more like 50 on the highway.  With your riding style, it also sounds like you should be getting at least 44 and up to 48 mpg around town.  I've absolutely flogged the bike and ALWAYS get over 40 mpg without question.  Even running hard is usually mid 40's.  I get about 44 mpg around town and 48 on the highway with the high performance tune and exhaust.
 
Now gearing could have been changed, and that would affect the mileage.  If you are doing dead on 70 mph at 4000 rpm, then that is stock gearing.
 
Just some more info...

the original and needs a reload? Although I'm guessing its flash memory
and doesn't corrupt easily, worth trying.

The highest I've seen was 44 mpg on the very first tank, when I was 
still afraid to use much throttle, and kept highway speeds below 90 
because of the questionable rear tire. The bike had been sitting for 
a year, regularly started but not ridden according to the seller. I 
thought mileage might go up a little with fresh oil and getting 
loosened back up after sitting a while, but as I got comfortable 
enough to use a bit more throttle, mileage has dropped instead.

Around town, my normal shift point is around 5K rpm, steady state 
cruising around 3K rpm, never normally using more than about half 
throttle. Doesn't seem like beating on it to me, but everyone has a 
different opinion. On the highway, rpm stay pretty much between 
5000-5500 the whole way, depending on traffic.

I asked the tech guy at the Boynton Beach Triumph dealer about 
updating the tune, he said as long as the bike was running well, 
there was no real reason to update it. He seemed to think it was 
better being a little rich, because the leaner tunes led to "lean 
surging" at steady cruising speeds.
