i am fitting a full akra system, bmc race filter etc to my 08 r6 road bike. also do lot of trackdays.

after a bit of looking up on net i am unsure which to fit,

-power comander (and map)

or

-yamaha race ECU.

does anyone no as to which is better to use, pros n cons etc. heard that the race ecu gives better performance but unsure if it affects rest of bike for road? can anyone help me please

I presume that both are adjustable for fuel mapping, so the decision must be which is more adjustable and which is cheapest.
