I'm going to get my 99' s3 remapped to 270bhp (AMD) and i'm struggling to decide weather to get a diverter or a dump valve ?? /ubbthreads/images/graemlins/confused.gif I do like the noise from a dump valve. Is a dump valve as easy to fit as a diverter? Either way im thinking forge or baily. I know this subject has been discussed many times before but can anyone help?
