I am a little confused, will Guzzi Diag reset the TPS on the 15M

No, Sir. The TPS is set with a quality voltmeter to 157 mV with the throttle plate completely closed (linkage released, high idle cam released, right idle stop screw backed all the way off, clean bore and plate edge, and perhaps even lightly zip tied closed).  This effectively indexes the map to the throttle angle.

It is a fiddly operation as the TPS is so very sensitive. You will get a feel for how much it changes with the tightening of the fasteners and take this into account until repeated attempts finally produce the desired value.

Changing the fasteners from the factory Torx/star to hex drive and obtaining a Casper's Breakout Harness (or equivalent) are helpful.

It strikes me that throttle plate position/TPS setting are the one constant in the process. All other alterations to fuel flow relate to the position of the throttle plates and consequent airflow. Unless...

So any map changes and it has to be reset

Nope, the TPS provides a voltage to the ECU that depends on throttle position. The ECU interprets that voltage as throttle open angle, no matter what map you use. 

If you have a later model, eg Griso, things are different

So if Todd reflashes the ECU on 2002 Lemans will TPS have to be reset manually

 

Im learning but Im used to doing everything electronically

No, and why are you getting the ECU "reflashed" when Guzzidiag is available.

I need to spend some time on that one I guess 

 

The TPS baseline is part of a "Decent Tune-up."  Personally. I would go this route before having someone alter the map:

I recall @MartyNZ is running a Meinolf map; not sure if it is v.93 . . .

Yes, I'm running Meinolf's v93, and I'm very happy with it.
