After much anticipation I finally got remapped by Nic from Tuned n' Styled Tuned n' Styled Engine Remapping & Chip Tuning (ECU Remaps) - East Midlands
This incorporated the DPF being gutted and the EGR being mapped out. The car feels more responsive, has more power all through the rev range, and is generally much more drivable. Ended up speaking to Nic for about an hour due to an extended test drive after the map... rolling road eat your heart out!
To top off the weekend I finally fitted (after colour matching) the Cupra-R splitter, and I've gotta say it makes all the difference to the front end. Think I will be able to live with the SE bumber without upgrading to an S-line now... AND fitted some new embossed aluminium number plates to boot! The car's been pampered this weekend, tuned, washed, waxed & driven with enthusiasm
