wow thats good ... mine is 1litre to 5.5km cruise

Mine about 310km on 39 litres. Use 97 and not so heavy footed ;)
i am using blitz ECU :) but engine is mostly stock. I have quite a phobia in doing heavy mods to the engine. If it ain't broken, don't fix it ;)
anyway, i think fuel consumption wise, its not bad for a sports car. My brother has a H22A on a honda prelude and the consumption is even worse!
i pump full tank, can run for ard 300km.
didn't really compare to other cars,
so dunno whether its high or not.
