Very interesting thread for me, this is, as my V70T5 is also lacking "vigour", I'm sure it's not boosting anything like as much as it used to.
Sorry for piggy-backing onto this thread, but I think I probably need to look at replacing my TCV and vacuum pipes too. Can anyone tell me what diameter vac pipe is used to and from the TCV please? Also, any good sources for non-silicone vac pipe?
Thanks!
