Hi thanks for info so far. Reason I want a custom map is, I worked at Honda for 12 years and although a batch of cars were identical in engine and spec, some definitely felt faster than others, my point being every car is different. I do like the idea if a big company who has put lots of money onto research but not all engines are the same. As for the remap and dsg I spoke to shark and that's what they told me with 25% off till end of Jan. Even said they would rolling road it for free! It's a 3.5 hour drive each way.
