Thanks for that tip I will do that. It was more the whoosh sound when changing gear I was after but as I said I don't really know much about dump valves to be honest. Iv seem some on eBay and heard a lot of people say they have forge dump valves. If I was to replace the standard dump valve to something like a forge would I gain anything?
I have been told I will gain an extra 40 bhp roughly with my remap so looking forward to that.
