Hi there people, first post

Just a quick one really, I pick up my new mark 4 golf gti turbo (150bhp) on Saturday and I am wanting to fit a dump valve on it?
Is this a stupid idea as it causes a lot of complications or can it be done quite easily?
I have been looking at the Bailey DV26 'EVO' or the Bailey DV36 'Venturi' - Any recommendations??
Cheers for any replies

Goody
