A std GTI will make 210 on rollers give or take 2-3%. A ed35 will make 235 give or take the same. Its as simple as that.
I did race a remapped ed30 against a revo'd mk6 GTI. It was a close call but pulled from me in every gear. Over a 1/4 I would say a couple of car lengths at most although he did have a slight jump.
Sorry but don't agree. There's plenty of evidence online to show MK6 GTI's put out 220bhp+.
As for against the mapped Edition 30, don't agree either. I've raced plenty and they are level pegging. You had plenty of issues with your map, and my friend running REVO had issues whereby his car wasn't running what REVO told him it was running.
Over a 1/4 mile a couple of car lengths translates to a huge difference between cars. I think you may be exaggerating.
there was LOTS of this going on over on the mk5 board a few years back. Many claiming their cars made bigger figures. In the end it was settled on a properly set up DD rollers. The result??? All stock cars made almost exactly the manufacturers claimed bhp.
There are so many variables on a RR... the only way of deciding is to try before and after a map to check the difference. It really is that simple.
My car was putting out 209 bhp before revo, and 264 after. Same rollers, same variables. the ed30 was pulling on me although like I said he had a very slight jump. A mapped ED30 will make a respectful 270bhp. So like I said not much in it.
So a difference of 5 horsepower is sufficient - in cars of equal weight, transmission and drievtrain losses - to result in one car noticeably pulling ahead of the other?
Technically you'd be correct, but in reality there is going to be no difference. You would notice a bigger difference simply by using better fuel.
Admittedly though, dyno figures can be a bit of a lottery (although I find it interesting that so many independent testers have yielded around the 220bhp mark for the MK6 GTI's).
Even still, the 25 horsepower advantage the Edition 35 holds out of the box is hardly enough extra grunt to pull out and pass an accelerating Mk6 GTI. Side by side the Edition 35 will nose ahead, but if you expect any more then you're going to be disappointed.

There are a few factors such as DSG (equipped in the GTI), AWD transmission loss, and the US Spec of the R (which is rated at 255 PS rather than 265 PS), but even still the 45 horsepower advantage of the R is hardly enough to pull drastically away from the GTI.
