Not sure what else is on that bike. That was sent to me by the tuner I use, one of the updates on their maps.
Apart from the reasons you mentioned, charcoal canister was removed due to it can back flow into tank leaving small particles of charcoal, damaging fuel sender.
Velocity stacks, small power gain. Crank case breather, so it does not warm the intake and no oil in airbox, small power gain. Removed airbox air pump as there was no need for it. Flap delete was because some people mentioned it rattled when mapped open. All these little changes should compliment the tune. Will be having this done at the beginning of June after service. Will feed back then with results.
You should ask RS2E, if you have a firmware update will your map be wiped.
