i put mine on today, sounds gorgeous. Quite loud and i fitted it the same way as in the picture in the instructions.
I got no rattle when i fitted it but when i turned it two full turns clockwise i had a drop in boost, down to about 6-7psi (LC), so i turned it back anti clockwise til it couldnt no more as it says in instructions when fitting, and it seems to be at about 8psi
on idle sitting above 20InHg is this right? its running ok, no warning lights, no faults on VAG-Com, just not up to 9-10psi as it was on my 007P
I still think its a lot nicer and reasonably loud! VERY IMPRESSED
P.S i didnt turn it two full turns after fitting will this cause any problems? I didnt turn it cos of the loss of boost
