Problems with exceleration in a 02 B6 1.8t
 

I have a 2002 B6 1.8t and under harder exceleration it will flutter, it feels like the boost or fuel kind of comes and goes. Under normal exceleration it is normal but when you go to about half throttle it starts to give and go. Other than that the car runs fine it has 63000 miles on it and has just been serviced at a dealership and they didn't come up with any codes for it. Has anyone had this problem or know what it is.

What sort of gas do you fill it with??? I use 94 Octane all the time

I have been using premium 91 or 93 if they have it but I just got the car back and I don't know what the other person was using before me.

Check the diverter valve. If you have the stock one, the diaphragm probably tore.
