If and when the new Rocket maps become available, and if they conform (same throttle positions and rpm’s in the tables), people with earlier bikes will be able to copy the new tables into the older base maps. Since they didn’t do anything to the engine, the added power must be due to derestricting the electronic throttle, as Penner has done. The tables in the latest Penner tunes will probably do the thing to your 2020, by all accounts. No need to drop $26K for more power.
