Hi- have a 2001 S4 Tip with Chips and new BPVs. Car has much more power but I notice the rush of power seems to dip in the higher RPMs. Almost seems like a boost leak. What are the common things I should replace? Has anyone had this before?
Thanks- Mark

 

Yeah, I had that. Same car. T'was a small tear in the Y-hose. Seems you can buy an aftermarket one that holds up better. Mine was under warranty. Good luck.

 

are you talking about the tbb? btw did this throw a cel?

 

i just ordered the Samco replacement TBB. Should have it within the week. then will install and report back. Car has 65k on it and don't know last time this was swapped out. I did replace the DVs two weeks ago.

It was the vacuum hose fo me. right when boost was supposed to kick in it felt like there was no more power.
