No idea what supporting parts might be needed, sounds like none. Impressive.

Turn Your 2018 Honda Accord 2.0T Into a Civic Type R-Beater for $695 - Motor Trend
Using Hondata’s FlashPro device, the company claims gains of between 10-40 hp and has posted a dyno sheet of the Stage 1 tune that shows increases of about 10 hp and roughly 40 lb-ft. When Hondata put a factory Accord 2.0T on a dyno (see the video below), they recorded a baseline of 266 hp and 292 lb-ft to the wheels, well above Honda’s advertised power ratings. The estimated gains are based on those dyno numbers, so that puts the Stage 1 reflashed Accord at 276 hp and a healthy 332 lb-ft to the wheels using California’s 91 octane gas. That’s already more torque than the Civic Type R makes (306-hp and 295 lb-ft).
If Hondata was able to get 10 hp and 40 lb-ft from this tune, imagine the torque increase from the tune that gets you 40 hp. Well, we don’t have to imagine as Hondata posted a video of the dyno run with the Stage 2 tune showing peak torque of 375.8 lb-ft–a gain of about 80 lb-ft over Hondata’s baseline figure. Additionally, the Stage 2 reflash adds 50-55 hp in the middle of the power band, which is said to dramatically affect the driving experience.
