After putting my head back on the S6, the fault i was chasing is STILL there 
It hangs back and surges in stages feeling like timing being retarded or fueling issue or something.
I've changed litterally EVERY electrical component in the engine bay, along with a genuine Audi fuel pump, spare ECU's and all the usually obvious culprits. The car is on samco boost hoses and an URS4 metal intercooler and has been checked and has NO BOOST LEAKS!
I've logged some readings on my VAG-COM but have no point of reference from a 'working' car.
Would anyone be able to tell me if any of my readings are a mille out if i mailed them to them??
