Nice. Time I got the RS6 remapped to maintain the bhp-delta.
I think I'll get the OEM reversing camera fitted (which will update the build sheet that Merc hold to show it as factory fit) and call it a day on the mods, and continue modifying the fuck out of the 911.
E63 (550 bhp) is £650/year, so a £200/year increase over the C55 (380 bhp).
All being well I should collect this on Saturday.
