Hi all, I know this has been thrown around the forum time and time again but I'm still left with different answers. I have just got my S3 8VFL and I want to look at a stage 1 map. however I understand if we go down the Revo route it will cause a TD1 flag that cannot be removed. I have seen other options like a DTUK box but it appears there has been issues with the S-tronic clutches slipping as the boxes cannot control the max torque. so, what tuning can I do that can be restored so I do not void warranty claims. all advice welcome.
