I'm about to put 66mm 12.5cr wiseco pistons in my 300.

The ecu is re-flashed, but is still stock timing (From 10° BTDC at 1 300 r/min (rpm)31° BTDC at 7 000 r/min (rpm)) if we check in the manual. it has about 43 hp to the wheel at the moment with stock piston and the reflash.

I would prefer to use pump gas (91 shell v-power) but can go with some race fuel and make my own mix (Sunoco 98). Also, can I put a +XX% on the power commander to start the dyno test (ex: 335/296 = 13%)?

It's a track only bike.

Any advice here from racers?

Thanks
