Just fitted forge dump valve kit with blanking plate and it don't seem to be working can anyone help it sounds like there is a leak from the valve
U should put a dv, anyway, now the leak could be on the b. plate, the most common is to sweep the screws.
Update ! I have taken the dump valve apart and it was the O ring inside had for stuck all fixed sounds awsome
Hi Hazz, I just bought The dame for my megane RS III, could you please send me a picture how it looks like, and if you got any vid! Does it make any difference in power/ driving?? Cheers
