I don’t normally leave reviews, as I expect a good service when you pay for one, however on this occasion I believe one is more than due....From my first email asking several questions, about the remap, about my car, warranty and general information, I got nothing but honest, helpful and informative answers.The Remap itself I was a little bit worried about at first but my mind was put well at ease with the depth and knowledge of the technician who installed it. Once it was in and we went on the test drive I could feel A slight difference, more responsive and more power lower down the Rev range, couple that we the exhaust note in Dynamic mode, I was more than happy.To note the real joy set when I took the car over the moors and gave it “some beans”A great improvement and if anyone is on the fence like I was, don’t be, get it done.The last point i’d Like to make to CT is your dealer Jordan, at Jordan detailing -Greater Manchester is a credit to your company, very punctual, well mannered, extremely professional and most of all his knowledge and attention to detail is second to none. So a big thank you to him and to yourselves.Great service all round.

I had a Stage 1 upgrade. The technician was very helpful, answered all my questions, was quick and tidy.The change is huge, economy, better torque, acceleration, steering and breaking. Its turned it into a different car, quick and fun in the corners on D mode yet happy for day to day on A. You will not be disappointed.

Hi, just a quick note to let you know the car is running faultlessly with more power everywhere. The work you've done has transformed the way it picks and pulls through the gears.

Many thanks for the work you've done, it was first class.

Your man was here prompt and on time and he was extremely competent, informed and professionally so please make sure you pass on my thanks.

Great service end-to-end, and from the brief run out in the car, plenty more power from the remap and a racier exhaust note in dynamic too, over all I am very happy.
