Our famous Synergy® tuning chip range, also known as Synergy-RonBox, or just Ronbox are designed to complement & enhance your engine, giving:

  • IMPROVED FUEL EFFICIENCY SAVES FUEL

"Can not believe the difference in comparison to a remap it's a bargain. Thanks"

    They produce a smooth increase, and work from very low rpm, filling in the holes in the torque delivery manufacturers have to engineer in as well as boosting the performance to new heights.

    Choose from a low cost Synergy 1 or for even more performance, a multichannel Synergy 2 or 3 and for selected older non common rail engines you need a Synergy 4.

Reprinted with kind permission of the editor.

FROM 1ST JANUARY 2017, WE'VE RE NAMED THE SYNERGY 2B TO SYNERGY 3 AND THE SYNERGY VP TO SYNERGY 4.
