Cheers for the replies guys, I have ordered a Revision G diverter valve and will fit this anyway and see what its like, as this is my first turbo car (always owning diesel audi's im failry new to the petrol turbo area, hence the reason i joined here to find out as much as i can. I will fit the new valve tomorrow and see what happens. I'm hoping its just that as i've only had the car a week, i think the cam chain and tensioner might need doing to once warmed up car sounds like a diesel, i am looking for a decent garage in the Brighton area if anyone knows any.
any more tips would be helpful guys.
many thanks
