I have just had the upgrade on my 09.10 3.0 HSE. The result of which is totally eliminated turbo lag , flat spots , ect. MPG now up from 21-23 around town to 27-30 on a 100 mile run now 32-37 as apposed to 22-24.

If I has kept a detailed log of my usage I would taking action to recover 50% .of the amount spent on fuel over the past 6 months.

I note EVO magazines demo car is maxing out at 22MPG.
