any particular brand of octane booster?
What oil grade and quantity are you talking about Dave?
I have been using Silkolene Pro Boost as an Octane booster - by far the best of the Octane boosters I have used - and the only brand that I am convinced of that actually raises the Octane by 3% so that a 98 fuel can be raised to over 100Octane.
When I was in Japan last year I noticed many forecourts with 102Octane - now I'm pretty sure that would get the GPX up to 200BHP.
