Supercharged
For the purposes of this thread, the bike is a 2010 Roadster with TOR + RamAir with standard headers and standard crossover.
The bike was already running the crowdsourced-enhanced 20355 tune with 10% extra fuel thrown in to accommodate the RamAir.
The aim of the dyno exercise was to validate the existing tune and optimise the air:fuel ratios where necessary. I wasn't expecting huge increases in torque or power as I thought the tune was pretty good in that area to start with.
Results:-
Below are the dyno graphs ...

Results:-
- The bike was pretty lean from about 5500RPM+. You can see this in the way the power and torque drops off. An additional 30%-ish fuel was added in the F tables in this area to fix the air:fuel ratio.
- L tables were way off. An additional 10% fuel was added across the entire table. With 40-50% fuel added in the area between 1050-3800 RPM and in the bottom third of the Air Pressure range.
