Top 5 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.
These chip tuning boxes use a wiring loom that splices in between connectors on the car. These 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.
Installation on most cars should take less than 15 minutes.
Please note. “Top 5” refers to the famousness of the companies and not the quality of the products. We have not tested these products back to back so we cannot comment on product quality.
