We had our Iveco Daily remapped by West Wales tuning as it had a flat spot at low revs. Iveco told us that was just how it was, but frankly it was actually dangerous to drive. After West Wales worked their magic the power delivery was vastly improved and the total power was increased. The bonus was it used dramatically less fuel once they remapped it. We can’t be scientific about it but we reckon we had saved more than their fee on our first drive alone. (To the south of Portugal). As a result of this experience we have now had 3 other company vehicles remapped by them all with similar excellent outcomes.

Had my Volvo Penta D3 remapped from 160 to 190hp. Fantastic efficient service with quick turn around. The boat now performs far better than it did as standard!

Absolutely delighted with my new remapped ECU on my Arvor 210. It has completely transformed the performance. Thanks Martin.

I have recently used west wales tuning to increase the HP on my Honda outboard. The service and communication has been excellent throughout and I then received exceptional aftercare. I had an unrelated issue to resolve with the boat that was new to me and West wales Tuning couldn't have been more helpful. Forthcoming with information and advice. Highly recommended company with service to be admired.

An excellent job. Engine performance has increased considerably. Boat speed increased from 32kph to 44Kph, ground speed. Many tanks for this upgrade.

I used these guys to remap my Skoda Octavia MkIII Diesel VRS 2019. Basically when I purchased the car it was for sensible reasons such as reliability and MPG for frequent trips to London. The factory performance however was a bit lacklustre and always left me wanted more. The REMAP performed by West Wales Tuning has transformed the car into something wonderful. It is now the car the Skoda should have made in the first place. The increase in power and torque is CLEARLY noticeable and the car wheel spins in 3rd gear with Pilot Sport 4 tyres on. Previous I had used a tuning box which is OK, but the remap from these guys is on a whole other level. SUPER IMPRESSED by the gains they have delivered.

Martin remapped my boat engine a Volvo penta d3. After spending two years trying to find someone that could map my original ECU I had almost given up. Martin mapped the ECU with a 220hp map returning it the very next day keeping my low engine hours. Now this guy doesn't sell his services enough one very happy customer 😁.

Brilliant service from Martin. Quick phone call and he was able to diagnose the problem which was confirmed when I brought the vehicle to him. Sorted out a dodgy remap on my VW Transporter which had been done by someone else prior to me purchasing the vehicle. Removed the original remap and applied a new one. Vehicle runs much better with smoother power delivery. Wish I'd been to see him sooner. Can't fault his knowledge and professionalism. Thanks

Martin carried out a stage 1 remap, taking the van to around the HP that the same engine leaves the factory but in much more expensive options! The result is a much more responsive and enjoyable auto gearbox, improved MPG, if i can keep the right foot light, as the vehicle has so much more torque that it doesn't labour as it used to! And as for power when needed, Wow!! It will never be a Ferrari but it brings a smile to my face now and again which helps the workaday existence tremendously. Thanks again, Martin.

Excellent and professional service received, my vehicles performance has improved considerably and will be passing on West Wales Tuning details to people that I know who are looking for modifications to their vehicles. Definitely 5 star service
