GT makes this technology available to fit ALL '00~current Guzzi. On newer Guzzi with 02-sensors, the base PC-V includes an 02-optimizer that handles all fueling below 40% throttle at all RPMs. The GT-Rx ECU Performance re-flash is required to give full fueling access to the PC-V. Adding an AutoTune unit without a GT-Rx ECU will require an additional 02-sensor bung, and per above, will not allow fueling below 40% throttle without. The GT-Rx ECU also provides many improvements for performance, pre-detonation and will also work very well stand-alone.
For those with a 15M/RC ECU Guzzi (Most Cali/Cal Vintage, V11 Sports, Breva 750 & new V7C) , please see this thread HERE for info.

1. PC-V w/02-controller $399.95: Power Commander V(5) - comes with 02-optimizer for fueling below 40% throttle -- the optimizer intercepts the stock 02-sensor/lambda wiring harness for dynamic fueling revisions below 40% throttle. 40% and above is handled statically by the PC-V. In development for the new dual sensor/lambda big blocks.
This does not address timing related issues such as pre-detonation (pinging), pop-on-decel or other performance timing ECU tweaks.
2. AutoTune AT-200 or AT-300* $279.95/$399.95: Piggbyback module to PC-V (only) above that provides real-time fueling changes, on-the-fly, as you ride... using a user-set Air Fuel Ratio (AFR). The AutoTune unit plugs into the PC-V module (ONLY) and allows you to pick/change your AFR, and your bike will auto-adjust, real-time, as you ride. Allows you to build/store a map for *your* bike by a simple click of the software, and store it on the PC-V... which then AutoTune will then use as a baseline to correct.
3. GT-Rx ECU $500: Static revisions, which include stock 02-sensor input delete, revised fueling and timing (for performance, cold start and pre-detonation) for any modifications you have done to your bike. If you change any bolt-on modifications, it would require another re-flash unless using above. This (ECU) mod can run stand-alone for drastically better running over stock. Not perfect, but very good. Requires TPS reset by VDST or your local dealer immediately upon re-installation of the ECU. This provides full fueling access to the PC-V/AT (above).
4. GT-Rx ECU/PC-V/AT $1109.90: Fully dynamic fueling revision for each second the engine is running, from idle to redline, with the power of the (supplied wide-band Bosch 02-sensor w/)AutoTune module coupled with the PC-V (mandatory). User adjustable fueling, and no need to visit the dyno for custom mapping. Any new modifications to the bike can be automatically corrected by AutoTune with a few keystrokes (OK, and often a little input from me.).
*NOTE: If you do not go with the ECU reflash and you purchase the AutoTune module, you will need to weld in an additional 02-sensor bung(s) in the exhaust for the AutoTune wide-band sensor(s). It is supplied with the AT unit. AT-200 is a single sensor/AT-300 is a dual sensor unit, one for each cylinder.

Instead of talking about POWER numbers, posted below are the Air/Fuel ratio graphs of % throttling.
The flatter the line, the more crisp the throttle response.
The 20% graph below is as delivered, OEM fueling. Red trace is as delivered, blue lines in the bottom two graphs (40% & 100% throttle) are from a PC corrected fueling on a Norge 1200.
