Thank you for the remap on my FORD BMAX. Carried out with efficiency and excellent service.

Your agent/ engineer was on time, most helpful and a joy to talk to. You could not have a more brilliant Ambassador for the company. While I did thank him I felt I needed to pass on my feelings to you.

From a very happy youthful Old Git.

Focus 1.6 Ecoboost Titanium X 147BHP to 209BHP and it feels like it.

It has transformed the car massively. Had it remapped just over a month now and managed to get 365MPG out of the first tank of fuel, which is what I was getting before the remap, and this included a lot of "testing". Driving sensibly at the moment and I think I will crack 400MPG.

Has a 14-day money-back guarantee but there was no chance I would have done that just based off the first test drive!

If you have a 1.6 Ecoboost, do it, you won't regret it.

Just want to express my surprise and thanks to you all at Celtic Tuning after mapping my car yesterday.

It was well worth the drive down to you from sunny Exmouth. I can’t believe how different my car feels and the gains you managed to get from my Ford Focus 1.6tdci.

Really didn’t expect to feel that much of a difference from a small Diesel engine. Even when driving home on cruise control you could feel it accelerating with more power than usual.

Thanks again

Had a remap on my Transit Custom, it went from a Bowyers Sausage (Stodgy and Lifeless) to a Peperami (Bit of an Animal) in an hour.

Excellent service, will use again
