Testimonial Mercedes Benz Reviews

Mercedes Benz E Class E320 CDI 204 bhp Diesel

Posted on 15th January 2019, 15:57

Jamie came yesterday from Coventry to remap my merc at the home address! He was very polite, friendly and explained very clearly what he was going to do! In fact, we got on so well that we had a good chat about cars, the weather, and life itself 🤣👍.

After approx an hour the job was done so Jamie advises we take the car for a quick test run and I was amazed at the difference! And totally amazed again after taking the car for a proper run to pick my friend up! Much quicker, so responsive and a totally different car now! Also, no black smoke just as Jamie promised!

Very very impressed with the whole experience and would recommend Celtic Tuning to anyone looking for an upgrade !!

Got my MercedesC220 chipped and the result wasamazing you can feel thedifference straight away, the pullnow is amazing andit feels a lot smoothernow which I am really happy about and the fact thatmy car is now faster than theC250 is a nice touch, theperson who did the job was really friendlyand going through theprocess with me and telling me how thisworks and how it works which was nice. It felt reassuring and I would talk about the fuel consumption butI’m still in the Honeymoon phase.

You need to get it done, I’m glad I did it.

Hi I have recently had my merc vito 2012 116 w639 in for repair at rm motors batley with dpf problems, caused by another tuning company that was unable to complete a job.

And basically I want to thank you for you for your services my van runs absolutely fantastic worth every penny.

This is my fourth vehicle I've had tuned by your company and every vehicle was unreal to drive. The first thing when I purchase a vehicle is to get it remapped .. My Vito I know I made a silly mistake and had it tuned by others not once but twice by two separate companys and had loads of problems right down to having to take it to main dealer to have a software upgrade on my ecu.

Next vehicle I will not hesitate so please keep up the good work.

Scott came and worked the magic on my car today.

The difference is tremendous, the car was spritely before, but now it’s a rocket ship ! No loss in smooth fuelling or tractability but just thrusting acceleration on tap.

Any reservations I had were unfounded. The guys at Celtic certainly know their subject.

Thanks for making my great car outstanding.
