Car is going for mapping on Saturday. Rs250 cup mk3 Mods are: Airtec ic Mid box chop Air filter And have just fitted engine dynamics turbo recirc valve with 1.3 bar spring... someone has just said to me that 1.3 bar spring is super strong and not ideal for many reasons? Anyone have any knowledge on this and any idea how much bar of boost these run after mapping? Cheers
