Sorry I can't let this thread just die but this simply gotta be the quickest and most rewarding mod you can do the twin turbo setup.
Thank you Rosssub!
I did this on my 2001 Rev D
Auto/Tiptronic and it's made the biggest difference. I've already been running a manual boost controller and luckily I hadn't thrown out the old T piece with the hose which has that restrictor pill in it. Took me less than 5 minutes to do the hose 1 mod. (Not counting me reading this thread over twice and a bit).
