Hey everyone, first post so hi to all. I've been searching the threads for this issue and haven't quite pinned it down yet....I recently bought a super clean 90 tsi that had been parked for the past six years, it had a new head, new turbo and a few sensors in order to get it running good enough to buy. Anyway I followed the maintenance guide and free mod page, completed everything, did a full tune up, checks on everything, found a ton of issues that I have mostly resolved except one...under WOT the turbo sounds like its oscillating or wavering, we we we we we we according the dummy boost gauge it also twitches between 8-10psi. It pulls fairly hard but it also won't climb above 5200rpm. Looking for any suggestions or knowledge...thanks!!
