I have a Leon cupra 180, and i wanted to get the Forge Split-R, i want the hissy sound of the dump valve and this seemed like a good option as supposedly it would stop the car going into limp mode due to being partially a dump valve and partially a re-circulation valve. Since joining however i have heard many people mentioning problems with the split-r. Apparently some peoples cars are still going into limp mode, some people are losing power, others cant set them up right... Someone mentioned i would be better off with a 007p? firstly what is the difference between a dump valve and a diverter valve? Secondly would i still get the sound? Thirdly are there less problems associated with a 007p? Thanks for your help, matt.
