Testimonial Jaguar Reviews

This is the first time I have used Celtic Tuning but I would definitely use them again.

The guy who came to do the remap was called Cameron. Courteous, friendly and even put up with some mindless questions from me. A top bloke.

The job was completed in an hour, exactly as he told me it would. As for the car, I almost had to make sure it was the same one. What a difference. In standard tune it always had quite a bit of torque but now it is unreal. And from just 1750rpm it just starts pulling harder and harder, with no dips in the power delivery at all. All the way to the red line. Very un-diesel like!! And It is so much smoother than before. So, thank you CT. You will be recommended by me to anyone interested in doing the same thing.

Amazing transformation of an already good car. Now drives like it should, power everywhere.

Highly recommended

I had my car re-mapped at one of Celtic's dealers, lakeside Garage near Heathrow. My car was good before and I was getting good fuel economy, but after the re-map not only has it got more grunt from the moment you pull away it is much smoother drive with more power it has made a very good car a car that I am more than happy with and I will be going back if I ever change my car again straight from the garage I buy from to get another re-map.

Thanks guys great fast & friendly service

If you're reading this it's probably because you're wondering if it's worth doing to your XF.

Well, after having the same debate with myself and deciding to go for it I had Kevin turn up last week. As everyone else has said it's a very simple process so I won't bore you with the details.

It's been a week now and the results are frankly better than I could have hoped for. I don't know if the figures are what is quoted but what I can say is that it's transformed the car. If anything it's now smoother in traffic in "boring" mode but in Dynamic and Sport modes it really flies. It feels slightly quicker than my old S4 Avant.
Low down torque is hugely improved and it belts you down the road far quicker than any big diesel should.
Oh and with cruise control set on the motorway at 70(ish) my MPG has gone from 39 to 45mpg (a 40 mile motorway trip daily measured in both directions over a week).

If you're wondering if you should go for this, the short answer is a very big YES!
