Well I had the remap today and instantly noticed the car would hold lower speeds in higher gears and was more eager to go. I couldn’t really floor it because of rush hour traffic but roundabouts and hills were much easier so I’m pretty happy.

Kevin was simply brill and we both share an enthusiasm for cars. I’ve been advised it will take a few miles to bed in the power increase but I’ll soon be there so hats off to Celtic Tuning and would defo use again.

We have just had our motorhome remapped to improve fuel economy and driving command.

This has been the second motorhome Celtic Tuning has remapped for us, again what a difference the van is not only with fuel economy but how the vehicle drives with more ease on the road managing to negotiate the hills and flats with so little ease.

The staff are very friendly putting you at ease when you arrive, free tea and coffee while we waited in a nice lounge area for our van.

From the first moment I drove the car, you could tell the massive difference this work has done to the car; it feels like it should have always done. It does feel like a different car and the engine really seems to live up to its potential.

I do 40,000 miles plus a year and this car with 130,000 on it feels perky and fresh. I am looking forward to using the extra performance and the additional fuel economy when I am not!

(My previous car was reprogrammed and the manufacturer mechanics claimed it was the fastest version they had ever driven and I achieved over 54 mpg from a 2.4 TD on average over 100,000 miles).

Celtic Tuning is professional to deal with and would recommend this investment to anyone.

Celtic Tuning.. Where can I start? They did an amazing job on my car, and from the moment I got there, the service was excellent! Answering all my questions and offering me the all-important, cup of tea.

But back to the car, what a difference! You can really feel the extra power and torque, after the test drive I came back with a huge smile on my face, all thanks to this company and their incredible Re-maps.

I would and will recommend them too everyone, and will be taking future cars to them.

Thanks Celtic. Great job.. 10/10
