Testimonial Ford Reviews

Ford Focus 1.6 TDCi 113 bhp

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

Recently had my Ford Tourneo Custom 125 tuned by Celtic Tuning. Very subtle 200bhp upgrade which adds driveability and performance. To sum it up, it drives just like a Ford Focus, easy to drive, disguises the weight and adds capable performance to the whole package.

This is how it should have come out of the showroom.

I have been "Celtic Tuned" today. Kevin surprised me with a phone call telling me that he would have time to remap my car ... actually 3 month earlier than my initial appointment. It did not take him longer than 30min, and the car feels so much smoother and more responsive than before.

Thank you Kevin, great job!
