Golf 2.0 tdi cold air intake & exhaust?

Which cold air intake works best with full milltek exhaust upgrade on golf mk5 2.0 tdi?
What are the likely power gains or benefits like quicker turbo spool up in this combination?

Is it already remapped yet?

It's not yet but it will be once those are fitted.
Will go with- bluefin, revo or other available here.

I have an older generation TDI than yours, the airbox on your generation TDI might be better than mine from the factory.

I would get the exhaust fitted, then remap. Get a feel for it. THEN do the airbox.

Thanks, I have read of aftermarket units being substandard but i will definately go the exhaust route. Heard an A3 2.0tdi with just the downpipe fitted and it sounds great! However, im not looking for system which is drone loud.
As for the chip, has anyone actually dyno'd their diesels after to see if the tuning claims match?
Thanks again
