28 September 2026 · DC Remapping UK

The SEAT Leon FR looks the part, and this 1.4 TSI came in for our Stage 1 custom dyno tune so it could drive the part too.

What it feels like

On a 1.4 TSI the extra torque transforms how the car drives. It pulls harder through every gear, needs fewer downshifts, and the power keeps building right up to the top of the rev range.
