Hummm... I see you have already met the kids...
Couple of things... use sentences and punctuation in your posts... huge blocks of text make reading very tedious and most people are unlikely to take you too seriously (hence the banter...)
Be clearer in your posts... you have opened with a post that looks very similar to all the 'got a car, want powaa, what BOV' type posts we typically get...
Anyhoo... as you have now been pretty much dragged through the ASN initiation process I'll add my two pence worth...
For a consistent 400hp (not the cold run type of 400hp) you will need to be looking at a GT3071r (preferably with a billet comp wheel etc from HTA and similar), tubular exhaust mani, external wastegate (38mm or 44mm Tial), 700-800cc injectors (Bosch 750's from 034 work well), large inlet manifold of some description, (SEM, IE etc), large FMIC (welly cooler or AH Fabs V2 work well), 63mm charge pipe work, 90mm or 100mm inlet and an RS4 MAF housing, rods, full valve train (springs, valves etc as GT30 and above prefer revs...), large port head.... other niceties (budget dependant) is 2ltr stroker (can't bore a 20v to 2ltr, use a TFSI crank and 83mm pistons...), WMI, full bottom end build using ARP bolts and studs etc as needed...
As you are from SA and can pretty much touch the moon then a std 3071 may not cut it... a GTX3071 maybe more effective...
Take a look at Staceys build (linked to earlier on the 1st page of this thread) as thats potentially where you want to be..
As for jap style tuning, this has no real place in VAG tuning... ME7 ECU's are a different beast altogether... ME7 can be tuned for 600 plus hp easily with no need for piggy back ecu's or other such non sense in fact ME7 is so tightly integrated into the cars architecture that I am not even sure its possible to do without more effort than is humanly needed...
You will need a decent tuner to get the best out the ME7 ECU too... something us Brits don't have to worry about as we have Badger 5 and R-Tech who are the leading tuners of our beloved 20v motors...
If you plan to learn ME7 then be warned its a steep curve... there are 100's of tables involved and finding the ones you need may take you a while... ME7 is a load based ECU... all revolves around the MAF... if you want to keep proper use of the haldex then stick to ME7 and get a performance haldex controller... if you want to fast track then stand alone maybe an option but... the electronics on these cars all talk to each other... removing the ECU will make certain systems inoperable so you will have to go to lengths to sort all these issues out... haldex, ESP, ABS, dash etc... all tied in... remove the ECU then expect to spend time pulling bits out, recoding stuf and god knows what else to do the job properly...
There are standalone haldex controllers available I believe, one from SQS is a simple mechanical valve (as thats essentially all the haldex controller is but uses electronics to control the valve...).. flip side of this is it will lock the rear wheels up on slow manoeuvres as there is essentially no centre diff...
No mention of budget so I could go on but the basics are above and in all the posts Karl etc have put up for you... look at the builds, do a bit of research then by all means ask the questions...
