Volkswagen ECU & Gearbox Remapping in North Somerset & South Wales


MTechTuning specialises in professional ECU and gearbox remapping for Volkswagen vehicles, delivering improved performance, drivability and efficiency while maintaining reliability. We provide a fully mobile VW tuning service across North Somerset and South Wales.


Specialist VW Tuning Using Dealer-Level Diagnostics


Volkswagen vehicles are well known for strong engines and everyday usability, but factory software can limit their full potential. Our VW ECU and gearbox remaps are designed to improve throttle response, torque delivery and overall driving performance while retaining safe operating limits.


All VW tuning work is carried out using dealer-level diagnostics, with full vehicle health checks completed before and after tuning to ensure reliability and consistency.

VW ECU & Gearbox Remapping


Pairing VW ECU remapping with gearbox remapping allows the engine and transmission to work together more efficiently. This can improve shift quality, responsiveness and make better use of the available torque.

VW Tiguan and Touareg 

VW Transporter and commercial vehicles 

Petrol and diesel VW engines
