Thought I'd better mention my car has an Invidia Gemini exhaust and I feel the economy slightly improved since fitting this ( and sounds how a 370 should)
24/25 mpg around town down to around 18 mpg spirited driving. 32 mpg up to Halifax two weeks ago at 70/80 mph on mainly motorway.
I find if I don't reset after some spirited driving the average never seems to return to better figures. 2009 370z
Just joined your site and would like to say hello to everyone and what a mine of information this forum is, and hope to meet some of you out and about.
