I used to use the 100 octane but mazda told me that the rx8 only reognises up to 98 octane so I changed back to regular optimax 98. Do you guys know if rx8 can improve performance wth the 100 octane?? I'll chage back again if so..

Plus V-Power Racing has 5% ethanol. I've tried V-Power Racing and I get better performance from BP Ultimate (98 RON) than V-Power. The difference is very slight though. Another difference is Fuel Consumption. V-Power is a bit more economical than BP but I still fill up with BP anyway (Thank You BP Card 
)

On the contary, I want to dyno my car (tuned by KnightSports) vs normal ECU.
I want to dyno while the car has 1/8 of V Power and add 40L of V power racing and see if it makes any difference in figure.

Matt,
Have a chat to your service manager about the 170 v 177 power issue but from what I understand, the answer is no - you should still have the 177 (if that be the true figure anyway).
Otherwise, I agree with Andrew on octane. I alternate between 95 and 98 depending on what's available and notice no difference whatsoever.
