Here's the list:
Swap over from old car:
Exhaust (including downpipes)
Both ARB's
ECU and TCU (including the maps!)
Seats and carbon trim
RS6 logo mats!
Laser Park Pro
XCar Link
Road Angel
Fit Wagner Intercoolers (modify existing shrouds)
Replace both Engine mounts
Replace both Oil cooler pipes
Replace Camshaft Position sensor
Replace all small Vacuum pipes
Cam cover gaskets replaced
Gearbox service
Replace rear gearbox oil seal
Dyno to make sure everything is 100% (Found TC definitely not locking)
Remove gearbox
Ship to US and full recon by 517 Trans ("Bullet proof"!)
Return and refit gearbox
New Lambda sensors (while engine out) just in case!
Full ATF change following finding debris from coolers in system
Dyno and full tune to max torque
Further full ATF change at 5000 miles - just to be sure - also small mod to ATF pick-up pipe.
Full DRC check and pressure (it is all fine!)
Four new tyres and wheel alignment (didn't bother with TPS)
Three defective parking sensors changed
Replace Passenger door lock
Replace GPS puck
Oh - and a routine 10,000 mile service!
I'm not even going to begin to go near my calculator to add it all up - but newbies beware, getting these beasts right takes time and money!!
Having said that, the car now dyno's at 527BHP and more importantly 880Nm torque, pulls like locomotive from low revs, and simply flies!

Enjoy your motoring!

Oh and thanks to Brett for a very enjoyable excursion in his C6 RS6 this morning at MRC - 750+BHP with Water/Meth Injection! Very impressive drive and ride, though not sure how much quicker than mine - somehow lacks the "character" of the C5, and the dash is too plasticky and too many knobs and switches!! Great fun though!
