Does the ECU respond well to increased octane? I know that not all engines will advance timing and spark beyond what 93 will allow.

My Volvo R responded VERY well to increased octane levels. Guys would run Torco additive, which worked well but left a reddish film on the tailpipes...which means who knows where else it was leaving a film.

Guys running race gas used to call it "cracktane", lol. The added pull was noticeable.

Heaven is where the police are British, the cooks are French, the cars are German, the lovers are Italian and it is all organised by the Swiss.
