Got car back from the garage last night, it had been in and had all the head reconed new head gasket stem seals.
i have a dump valve but for some reason this was not dumping i was just getting wastegate chatter and a very high picted whooshing when car was boosting,
so i took the boost gaugue out and ran the dump valve straight on to the vacume line this made the dv work but it is not as loud as it was and i am still getting the high picted wooshing on boost which also seems to take longer to build up i have check all the vacume line for leaks and cant see any what could be causing this?
please help rep will be added for helpful input
