Is the Forge Recirculation valve needed if just doing a stage 1 flash tune? The car is a brand new RS275, so the oem rubber valve is still new. Thanks Robbie
I have replaced mines yesterday and mines a 2010 RS250. The original still looked okay and diaphragm looked in very good condition. It didn't make any difference. You can change it but no need to rush into it yet. Sent from my iPhone using Tapatalk
