Searched through other threads but don't seem to find any answers so I'll start my own thread
Ok so I have a problem with the running on my 1.8t. Standing still and rev in hard it borks now this also effects it when driving as it sometimes has power then other times it doesn't. I have put a forge split-r valve on as it runs better with this on(although not perfect) and I think it's because you get less boost with these valves on. If the standard one is put on it runs bad sounds like its on 3 pots. I did purchase a new one thinking that's what it was but still the same with a brand new one on.
scanned the car and get pressure drop between turbo and throttle
All help is much appreciated
