Any of the major players will do you a deal on a milltek and remap - AMD/MRC/Unit20 etc.

Regarding a decoke, it'll only come back after 5k -10k miles or so, so you have to question if it's worth bothering. It's a lot of money for minimal gain.

A lot of the loss of power on an rs4 comes from vacuum leaks which are often corrected when a decoke is performed. Best thing to do if you're not happy with the current performance if to get it on a dyno and see what it makes - if it's making 400+ps then probably not much wrong with it. It's it's making 360 or something it's likely a vacuum leak.
Carbon will cost you maybe at worst 20ps. But a clean, remap and an exhaust will give you perhaps 30 back so you got to ask... Is £3000+ worth 30hp? Probably not IMO.

I would seriously consider a Terraclean, but make sure you go to a place that has the S-Tool. Not all agents do. The S-Tool cleans the induction side, valves etc and removes carbon deposits. I had mine done the other day £180 and the difference is noticable.
A quick power test is to put her in 3rd, then time the acceleration from 3000 to 8000 rpm. It should be around 8.5secs if running the correct output. I did this test pre clean and the best i could manage was 9 secs.. Post clean I got and 8.4... Very pleased with the results.

They claim it's as good as a manual carbon clean and I'm confident (as are all the major tuning companies) that it's not.

When AMD/MRC/revolution/Unit20 all say the same thing - that it's no replacement for a manual clean - I'm inclined to believe them.

Sure - it can remove some deposits. But anyone who's actually done a clean and seen the solid lumps of rock hard carbon that come out will testify, no gas is removing that when it takes elbow grease and a scraper to get it off by hand.

I'm sure it improves things - but a replacement for a manual clean it isn't.

Agreed, its more of an annual service - get it blasted or even better a chemical soak, then Terraclean one a year to prevent build up again...
