Jason can do the posta-map option if that's any good?
See

Thanks Rusty. ..... I like the look of this. Few questions:
1. Will this still be relatively undetectable by BMW? As Emaps and DMS talk about resetting some software counter etc?
2. If so would it be advisable to flash back to stock when the car is going in for servicing?
3. Is there any stats on the potential 3 settings? , (power, economy or both) I. E. BHP/Torque /MPG

No worries,
1. If you take your X to the stealers and they 'do' any work to it as in updates etc, you will lose your map as they re-write the lot, which is why you can buy the 'magic box' from Jas so you can reset it to standard before sending it in, then rewrite the map of choice back when you get home.
2. See 1.
3. On a facelift 218bhp diesel E53 I think Jas said you will get approx +40bhp & torques with a sensible power + economy map, as well as and extra 3mpg ish too. I couldn't tell you about the E70 though, sorry.
All in all, I would recommend
