Its a common myth that the ED30 is faster than a R32... a remapped one, yes. Std no. 
Why would VW make another golf quicker than their flagship after all.
They did 
They haven't? Even modded vs modded an R32 would win - 500+bhp turbo vs 300bhp remap
ED30 is slower, will be close in a straight but be left behind on the twisty bits. GTI is slower noticeably.
MK6 GTI is slower than the upcoming Golf R (the new flagship)
Sorry, but I have to call BS!!!

Mine slaughtered an R32 at Spa Francorchamps...several times...in the wet...and I was on R888's. Just ask RedRobin.

To the OP. You have a good car in the ED30. Keep it for another year or so until the true MKVI shows its face and not the MKV.5

The MKV.5 is a good car, but it wasn't enough to tempt me out of mine for just a few silvery bits of trim and a faux LSD.
