Hi guys and girls, I picked my car up today after getting a few mods fitted, including a Forge CAI and full Blueflame TBE. It already has a Stage 1 remap on it at the moment, which I will be upgrading to Stage 2 in the next few days. The guy at the garage, where in fairness they are more used to working on MK1 and MK2 Golfs as well as others told me that I would need to upgrade my diverter valve as it 'would soon be going' because the car's mapped. I told him that because my car's a newer S3 it has the Revised Diverter valve fitted, but he said it wouldn't matter and that I should change it for a Forge one instead. I'm a bit puzzled, ..should I take his advice or should I just leave my diverter valve as it is? I've heard of guys on here swapping out their Forge items in favour of the OEM Revision D. Help me, please, lol!
