I have no idea what's causing the hot condition since the bike is probably not running too lean.

Good advice so far... Some of my 2 cents...
Ensure you save your custom tune to you PC and USB before reflashing the ECM.
Reflash using the base map from the calibration list, then don't adjust anything, but just start Smart tuning. When you reflash w/ Smart tune enabked, AFR all goes to 14.6 and it retards the itming by 4%.
Get good coverage, low to high RPMs, far left to far right in the VE tables.
Continuously compare base calibration VE tables to your latest VE table, so you can see the changes and what cells you might be missing. TTS does this for you, but unless you have another program like My Tune, you need to do this manually with SE Pro.
When you feel good about the VEs not changing much, create a map and adjust your target AFR table to what you want. Some people run a small closed loop area in cruise range, others use a larger closed loop section in the cruise range.
Go for a nice ride, adjust your AFR table or decel enleanment as necessary to eliminate poping (but if your VEs are good, poping will be very limited).
Then go through, do some basic recordings, not smart tuned, look for spark know, then adjust timing as needed. +2 at a time, no more than 45%. Then reduce where you get knock.
The bottom line, I would continue to push the Service Manager and dyno guy to get it right. There is something obviously wrong. I'd be curous to what their map looked like (VEs compared to base map they flashed, AFR tabel - all open loop?, timing - like you said no changes..). You paid good money...
