Testimonial Mercedes Benz Reviews

I had my SLK tuned yesterday. The whole process has been fantastic.Kevin drove up from Cornwall to my home in Kent and started the job at nearly 5 pm. Within 30 minutes the car had been checked for faults and the old map downloaded. Another 30 minutes later (and a cup of tea) the new map was loaded. The keys were back in my hand and all of my questions were answered. Kevin, top man. My test drive was completed, payment made and I sat down with a big smile on my face. Today I have taken the car for a longer run. She feels smoother and in S mode a whole lot faster. I can't recommend Celtic Tunning highly enough. They know what they are doing.

I'd just like to say what a great job you folks at Celtic did on the remap of my 114 Vito. When I bought the van, I was initially disappointed.

I called Celtic and the staff were very helpful. I booked the date and the tech turned up on time and did then work. A week later I called back to say the Merc remap file was not what is expected, performance-wise, Again the staff were very helpful and rebooked the tech to put the 240bhp file on the van.

The result was dramatic, it pulls really well all the way to high revs(I haven't tried past 3500rpm) although most of the time I drive it between 1200-2300rpm and its great such an improvement.
The more i get used to it the better the mpg i get .... drove it back from Lakes on A66 and got 49.8mpg average on the journey ...thats fantastic for a big van imo.

Thanks Celtic for the great job.

I had the stage 1 tune added to my AMG A35 today by Jamie!

I am over the moon with the difference in the car's ability now performance wise!

My main reason for contacting you all there at Celtic Tuning is to commend Jamie!

This Guy is a true Gentleman and conducts himself in a very professional manner! From start to finish he had every situation under control. He is an asset and a credit to you there at Celtic Tuning!

I am not on any social media sites, so this is the only way I can put something together in writing to pass forward to the senior management if that could be possible, please.

Once again thank you all so much, you can count on me to let as many people know of your great tuning company!
