Second car I've had mapped with these guys. This time by their mobile unit. 6 weeks later and still have a smile on my face. The guy turned up and was polite courteous and knew what he was doing. Will definately use again. Cheers guys

Had my Megane remapped at my own house on 31st of January. It's been 3 weeks since then. Car was quite quick before for a little 1.5 diesel. After the remap was done which only took half an hour, it is astonishing!

The car feels faster than most 2.0 litres and completely changed the way it performs. Before there were flat spots especially is 1st. But now it just pulls effortlessly and smoothly is every gear. Fuel economy has gone up a bit too! Easy 55mpg.

If you're considering remapping your car then I would very much recommend Celtic Tuning!

I had Kevin out today to carry out a stage one remap on my Renault Traffic works van, he was very knowledgeable and a credit to the company.

Well what can I say, the remap has totally transformed my van, the sluggish pickup has gone and it has become a lot more drivable.

Highly recommend Celtic Tuning to any one contemplation have a remap done.
