Just got my dump valve bung through off ebay (It was off a guy on here, sorry cant remember name) and fitted it, blocked off the vacuum hose with a screw for now and took it out for a drive!
Let it warm up and it feels sooooo much smoother and when I change gear I get a little bit of chatter!
Fitting the K&N later so maybe this will make the chatter sound a bit louder
Its much nicer to drive too but it does feel wierd not hearing the noise when I change gear!
