Noob alert!!! I'm looking at tuning options for my 2007 S3. I think the car is brilliant at the moment, but you guys know what it's like. My mate got his done at Star Performance (using GIAC software) in Fife and no doubt he'll reply to this post. I'm quite interested in the MTM package carried out by QS Tuning in Sussex. This consists of a new ECU and a full Milltek system taking the S3 to 330 bhp and 420 Nm . It doesn't come cheap so I'm wondering if the MTM remap will differ significantly from the one done by GIAC and does the Milltek exhaust system make a bit of difference. Any experience you guys have of any of these parts or customer service would be really appreciated. This would be my first tuning upgrade so would like to get it right. P.S. Would I get any better results from another combination (ECU/exhaust) and am I missing a trick with the remap options ? Thanks for any help.
