Probably been asked before but can you chip or remap the BMW diesel. If so anyone done it and to what effect...smoother, faster better torque or a waste of money. I know a rechip on the TD5 makes a real difference without hitting fuel economy so whats the crack on P38's?

Many thanks ........now what about the EAS is everything they say true
Personally there seems so many on the road LRO must have bought a real duffer as their project RR!
Try Rimmer Bros, Digital Powerbox 2. I have an older version, works well. A re-map would probably be better, but more expensive. Do a search, lots of info on this.
Did the powerbox improve mpg at all, or make it worse?
Is there a noticable difference once a powerbox is fitted?
These sites that sell the powerbox all recommend upgrading the air filter, is this entirely necessary or just a way of getting an extra £70 or so out of us?
