hi all,
just had a general health check from allen jeffery plymouth I'm sure most of you have heard of him did a full check over and also got rid of the litter and small remap but also noticed that i had a one way valve which was removed and was able to get full boost from this....however, the blitz dump valve does not seem to be loud or is it meant to be non existent noise?
compared to my mates Skoda octavia VRS i can hear it all the time
is there anyone around plymouth who can have a look with me or some advice on here would be great.
Thanks in advance.
