Chip Tuning Boxes – Top 6 Companies
The 6 Chip Tuning Box companies on this page make plug and play tuning boxes for petrol and diesel engines. These chip tuning boxes do not alter the factory ECU code so are not detectable by a main dealer if they are removed before going for service.
Before buying a tuning box…
Before making the decision to buy a tuning box, check the section at the bottom of this page
Chip tuning boxes use a wiring loom that splices in between the connector and the sensors on your engine. The companies on this page supply their boxes with the required cable making installation super fast and easy.
You simply unplug the connector on the car, plug it into the connector supplied with the tuning box and plug the other end of the cable into the original location on the car. Click here for an example video
Installation on most cars should take less than 15 minutes.

Wait! Before you buy a tuning box
Darkside Developments have done a video on tuning boxes (below).
In our experience of tuning boxes, their video is fair. We have always said that companies in the tuning box industry are under massive pressure to give a “power increase” number more than anyone else…
Because so many people base their choice of tuning box on this “number”. Our advice has always been to treat power increase numbers with a pinch of salt, unless these numbers have been independently verified (eg DTE have their products tested by TUV Austria)
The best way, in our opinion, to choose a tuning box is either look for an independently tested product with TUV approval or check forums and see what people with the same car as you think of the tuning box or boxes you are looking at.
With that massive proviso out of the way, here is the Darkside Development video.
If after watching the video you think a tuning box is still the best solution for you eg your car is a lease or your car is still under the factory warranty, you can buy many of these tuning box brands on ebay (Links below)
