Upgrade your brakes,even when at 300 horses they are not up to the job,I was finding myself consciously braking 20 yards in advance as no confidnce in them,R32 ones do the job

I think with the twintercooler, it's extra volume for the turbo to fill, so can be a fair bit of pressure drop there.
How about a MK6 R intercooler for around £250 from the dealer? OEM quality, bolts right in, cheap and there's proven gains which reduces intake temps on sustained high rpm pulls, so perfect for a KO4 engine.
Add to that a 3" downpipe (which usually stays 3" to half way under the car before joining the OEM system) and see where that takes you.
After that you can add an intake and cat back if you want more.
Just the DP and intercooler + software should take you to 330-340ish.
It's highly likely you will need a HPFP to sustain that kind of torque though. Loba is arguably the best, but also the most expensive.
Paradox1:
At what level does the stock catback become restrictive?

The standard system is 2.5", or 60mm or something, which isn't too bad. It's probably the big suitcase silencer that's the main restriction. Hard to say what the hp limit is but plenty of GTIs/ED30s make good power on the standard cat back :smiley:.
