I mentioned to my mechanic over the phone that I can't really hear the turbo anymore after doing HPFP, water pump, tstat, some other things myself. I have no codes per Carly, but he said I may have vacuum issue if I can't hear turbo. Performance is ok to me, not sure if its the best it has ever been but seems fine. Any advice on what values I should log (boost values) in Carly or other things to read out before I go chasing vacuum lines? They are original and 2010 35d with 107k. Thanks
