People using BLuefin, I don't want to be a party-crasher, but think about this:
Ed.30 has the same intercooler as normal GTI.
S3, which has donated the engine to Ed.30, uses a bigger intercooler, and that with only 265hp!
And now with 300hp bluefin conversion your engine and turbo are running quite a bunch hotter.
Maybe, for your own good, you should give some thought to a new, bigger intercooler and maybe an exhaust system with large bore downpipe.
Just my 2 cents.
