Right firstly i have extremely limited knowledge on this, so if any of the below post is completely wrong, excuse my ignorance.
I have an A4 1.8 20v Turbo (n Reg '96) and am wanting to fit a dump valve, or not as the case may be. i know dump valve dump to atmosphere as the clutch is pressed and thats what makes the 'PSSCCHHH' sound, but another A4 from round my way makes a more of a PSSCCHH-CH-CH-CH sound. i have been told tat this noise is made by taking off/bypassing the wastegate?
how correct is this or is this making no sense to anyone
Any help greatly appreciated
