Yes, you'll notice! Had Stage 1 Revo done last week after only a week of Ed30 ownership (part of the reason I got an Ed30 was tuning potential). Coming from a non-turbo car previously, I find the 0 - 2,500 rpm rev range a bit flat and laggy - but this is no different to the stock Ed30 and I'm sure I'll get used to it. But there's a big difference from 2,500 rpm and I'm particularly impressed by the in-gear urgency with the re-map. Enjoy! (I've recently posted my remap experience in the Revo Zone section if you're interested).
EDIT: Oops
- didn't read the thread properly as mine is an Ed30 ... I'm sure re-map on GTI will also give impressive results.
