SYNERGY

WELCOME TO 
TUNING DIESELS

Since 2005, we have been designing and manufacturing electronic diesel engine tuning units to complement and enhance your vehicle, restore lost performance due to out-of-spec sensors and improve the fuel economy.

Our famous Synergy® tuning tuning box range, also known as Synergy-RonBox®, or just Ronbox® is available for a variety of diesels at prices starting from just £99.95.

It includes diesel tuning products that produce a smooth increase, and work from very low rpm, filling in the holes in the torque delivery, as well as boosting the performance to new heights, all without causing problems at MOT time.

OUR RANG

Choose from a low-cost Synergy One to give older diesels a new lease on life, a multichannel Synergy 2a where the MAF sensor is affecting the performance, or a Synergy 2b for newer diesels and those not suffering from MAF problems.  

The optional dash switches allow you to alter the performance while driving – much like the 'sport' button fitted to some vehicles.

For selected older, non-common rail engines you need a Synergy VP. Our new Digiboosters are for controlling your turbo, thus letting you alter the boost, or fit a VNT turbo as a replacement of a wastegate type.
