You have also gained an extra 6 bhp,which might not sound like much but as the emissions rules get tighter and tighter for a power output to rise it means that there has to be a pay-off somewhere.
Hi, cheers for that.

I had previous car from new.
I do same now as before: Each fill up I reset trip comp.
Dealer say not to do that as wont get accurate reading. so for last 2250 miles/44 gals I not reset it; readout says 50.7. I did manual workout using receipts and got nearly 49mpg.
I figured the extra 6bhp would be offset a bit by the extra gear.
Is the computer fairly accurate for gallons used etc?
