Officially:

010 Dry conditions/leaded fuel
020 Wet conditions/leaded fuel
030 All conditions/unleaded fuel (010 and 020 discontinued)

In reality, very little, if anything!

It takes more than just an HRC card to make power. Using a card will likely not gain you a great deal.

TYGA Performance have claimed to have achieved 58.5hp from an MC28 without an HRC card. I would expect to see maybe a 3~5% gain if an HRC card was subsequently used on the same bike, although it would be wise NOT to then run the MC21 flywheel as they did. Consequently you would be adding around 3~5% to approx 56hp (the figure I would expect to see TYGA end up with using all the suggest mods and an MC28 flywheel), not adding it to 58.5hp (TYGA's results using an MC21 flywheel).

Edit: fuel types.

Any HRC card MUST be coded to your actual PGM-IV. You cannot fit just any HRC card...

Just like your ATM card, the HRC card has its own unique PIN which must be matched to your PGM-IV PIN. Think of the card as a security key to your ignition. The wrong security key (card) will not unlock the ignition.

I'm not saying don't get an HRC card, but I am saying don't expect your MC28 to suddenly want to lift its front wheel into the sky once the card is inserted!! Wink
