Ive been thinking about getting my 2005 E46 320cd convertible remapped. How ever, i generally use my car most of the time for pottering about really.
I was wondering what kind of gain on fuel consumption I would get if any. I heard you get about 10% increase on MPG. But if i was to be only pottering about would I notice an increase, or a decrease as i would have more BHP, would this use more fuel at lower speeds, stopping and starting more?
Or would you only notice an increase on longer journeys like motorway roads when your at higher speeds in higher gears when generally the MPG is generally alot better.
I hope this is coming out correctly! Any help or information on getting my BMW remapped would be greatly appreciated.
