Testimonial Mercedes Benz Reviews

Lol, where do I start ??? Took a trip to Newquay yesterday for a rolling remap at HQ.

The lady n gents where very very helpful and accommodating and I was extremely well-cared and catered for! The tech guys spent around 3 1/2 hours on my car and between them and myself established that my upgraded injectors were, in fact, wrong and my original injectors would suit better for now and that I need some additional parts but they did manage to tweak my car a bit more to the upgrades I already have and what a difference yet again to the car !! BUT they couldn’t remap my car not the day to what it was planned for and despite the guys spending way more time on my car than scheduled, I was not charged a penny and I really appreciated this along with all the time n effort the whole team put in to make me feel so relaxed after a 5 hour drive from home!

Very very professional, kind n friendly team all round !!! Would very highly recommend Celtic tuning to anyone !!!! 😎👍

I had this remap done a week ago and I can confirm that it has been very positive. It pulls much better in all gears, is very smooth and effortless and really goes when you ask it to.

I am not in a position to comment on the MPG yet, however early indication shows an improvement.

I am absolutely delighted with the results of your work.

The throttle response is much improved and the power curve is just as smooth as can be, I wouldn't have believed that just 30 odd bhp would be that noticeable!

I had a mobile visit from a nice technician who drove all the way from Cornwall to Bedford on our pre-arranged date and time. Remapped my ECU and totally transformed my E350 Bluetec.

The car runs smoother than when it was new. HP and more impressively the torque increase has made a huge difference. I would recommend Celtic Tuning to anyone. Fantastic customer care and very knowledgable.

Thank you guys for looking after me. Andrew Oliver
