No idea I'm afraid. I live in the UK and thus have no use for anything above 70mph.
However in theory it is possible that the top speed could very slightly be increased by the fact the car holds onto its power longer before tailing off at the very top end. This would be marginal though as the GTI has a K03 turbo which is designed for fast spool up at low revs and a lively mid range. The Golf R has a K04 turbo which would indeed have a higher top speed than a standard one as it is designed to hold its power higher up the rev range better than the K03. The K04 doesn't spool quite as quickly at low revs though, but this is marginal and its a very tuneable unit. In short, by far the biggest gain on a REVO'd GTI is in the mid-range where the added torque struts its stuff.
Perfectly happy with my K03 though (for the warranty period at least).
