WOW is it tuned?? thats very fast for a tdi isnt it? whats book speed?
currently stock at the moment, book speed is 135 although i think with a re-map could probably get a few extra from her.
the MK5 TDI book figure is 137 still no where near the ED30 though

I dont know much about the MK4 speed wise so I should probably not comment.
the final gear in the MK4 GTI's was never that long as the 1.8T was only 140 odd, the R32 on paper is 153, so the same as an ED30 (top end wise)
