Decided to have a go just to see how my last 60 hp gain looks time-wise...
And got nicely dissapointed.
Stage 2, 280 hp DSG Scirocco 2.0t gave me a hard time!
Every gear above 5k rpm lacked boost, totally! Everything was perfect till 5k and then just nothing, gear up, ok till 5 k rpm then nothing again.



Hood up and this is what happened:





First thought - clogged air filter, but it was replaced 3 months ago, checked - OK.
What do you think could have caused this? Any experiences?
Maybe just a 10 year old rubber part that didn't like 35-38C outside temp combined with temp under the hood?
You think I should replace it with OEM or maybe there is something else available from Samco and the like?
Thanks in advance!
