CGK Performance Ltd
Driving is our passion, happy customers is what drives us.

CGK Performance is based in Nottingham and was established in 2017. After having cars tuned by other companies on many of my own cars over the years i felt there was a gap in the market for a company that can be more flexible in terms of delivering a quality product to the customer via our mobile remapping service utilising our fully equipped vans while at the same time still offering local garages when needed.

After nearly 4 years in the tuning industry we have developed strong partnerships with local independent garages across the midlands to also offer fitment of performance parts and dyno development to push the tune of your vehicle further with custom mapping and data logging in a safe environment.


Our goal is simple, a quality product delivered in a friendly and understandable manner at an affordable price, no matter what car you drive. It's the CGK Performance way.

So what's so great about remapping?

Well everything. It makes your vehicle more powerful making for safer overtaking, gives greater performance meaning a better driving car, and all of this with greater economy if driving normally.

I Like the sound of this, what different type of maps do you do?

Generally we do three base types of remaps. There's Eco, 50/50 and out right performance. From left to right there's a decrease in economy but with the added benefit of more power.

Some seriously detuned variations of certain models can see gains of upto 80%. And all of this from a stage 1 tune meaning no engine modifications at all.

Is it bad for my engine?

The simple answer is no. All of our files are developed in house and tested on a dyno machine meaning that the file has been checked vigorously to ensure your vehicle isn't over stressed. Aslong as you keep your vehicle well maintained you can have many happy years of fun and service from a remapped vehicle as I have with my last 4 cars.

What will I notice most?

Firstly you'll notice the improved throttle response which generally we improve by 10%, the second thing will be the way it pins you back in the seat. Especially on the modern diesel turbos. The car will pull harder and higher up the rev range and after all this fun your having if you get it onto a motorway and have a steady drive to work you'll see more miles between filling up also. Win win!

What exactly do you do when you remap?

We would start by doing a full diagnostic health check on your vehicle. If this came back with a clean bill of health we would get one of our genuine software tools and read your ECU with it. This data is then sent to our in house software team who carefully modify it before we receive it back and safely write it back onto your vehicles ECU. After this we then go out for a test drive and make sure your completely happy with the results. 

How long does it take?

From us arriving at your house to us leaving you with a big grin on your face around 1.5 to 2hrs.

Why would I choose you guys over my mate Dave who can do it for £100 quid down the road?

Chances are your mate Dave is using cheap Chinese clone tools. Aswell as not being endorsed by the manufacturer they can also damage your ECU, potentially leaving you with a big bill, because Dave will have no back up from Ebay where he bought his clone tool from in the first place. On top of this if he can't afford proper tools I doubt he will using dealer level diagnostic tools which we do. On every single car we remap, and for free!

We are also fully IMI accredited meaning we have done training to know exactly what to do with your pride and joy.

What warranty to you offer?

We offer a lifetime software warranty which covers you for as long as you own the vehicle. This covers our software under the exceptional circumstances that it might become corrupted or be erased by a dealer service update. Another added bonus that this is completely free and wont be rechargeable.

On top of this we also offer a 12 month parts warranty on any vehicle under 90,000 miles. (please enquire for a quote for your particular vehicle)
