Boost rpm

<< < (3/3)

pudding:
What map is it?  It might not be that.  As you say, little turbos run out of puff quickly.  Not even the KO4 is a VTEC (yo!) mega master past 5000rpm either.
There is a ton of exhaust gas squeezing into a ridiculously small scroll.  Great for spool, shat for top end.  It's the age old compromise of Turboing.

Unless there are some significant hardware problems, I would say you're just underwhelmed by the GTIs performance.  Nothing wrong with that.  I know people who've grown up with Super bikes and even Ferraris are slow to them.

Have you checked the basics? PCV and the recirc valve? Those failiing will make it slower to build boost.
