Re: Octane Booster......
It will only make a difference if the ECU has puilled timing and is running a low IAM.
The extra octane will allow the timing to be re-advanced.
Some cars re-act well but only becuase the above has occurred.
If the ECU is running all, or close to all, available timing advance there will be little or no difference.
IMHO mapping for octane boost or V-power is pointless, as you end up panicking or being really anal about what fuel you put in.
Map it on a good branded SUL, if you want to put 98/99 or Octane in then it's your choice and only really there as a safety net......
