SYNERGY

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 £89.95

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, reducing fuel consumption and all without causing problems at MOT time.

Don't be fooled by high priced competitor products - you're paying for their advertising and marketing not a better product.

TESTIMONIALS

DIGIBOOSTER

If you wish to alter the boost pressure on your vehicle which has an ecu controlled wastegate or vnt turbo, you need our plug-in Digibooster 1.

This has 8 settings so you can choose the boost increase.

On the other hand, if you are replacing a wastegate turbo with a vnt type, you'll need our Digibooster S.

This is a standalone intelligent controller which controls the vanes on a vacuum vnt actuator. It has 16 settings so you can control the vane position at low and high boost.

OVER 120 SOLD TO DATE

It is easy to fit, does not affect your existing engine ecu and also fits mechanically injected diesels.

Available with or without our adjustable 1-3bar boost pressure sensor and Pierburgh boost control solenoid valve.

"I have to say I was a little sceptical that a little box could make a huge difference The service was great and I received it with in two days I plugged it all in set the box to 10 with the fuel and air on and I was blown away definitely worth the money thanks very much!"

Joshua
"Fitted box, maf and switch to 2005 freelander . I am totally amazed at the performance. Towing our caravan uphill in fifth gear and being able to accelerate when needed is unbelievable. Solo the fuel consumption is regularly in the low forties , brim to brim , or use the power to surprise Range Rover drivers ! I cannot recommend this product enough , utterly brilliant !"

Roger Sell
"Amazing transformation, box & maf. tired Freelander td4 turned into a new smooth & fast car. Steady idle, pre-turbo torque & more turbo performance. Haven't tried 9 or 10 yet. So glad I tried this, thanks"

"Finally got round to fitting the synergy 2 box on my freelander td4.After quick call to Ron , fitted the box - what a fantastic difference in all ranges and driveability - even sorted out a misfire it had ,really good investment good product,and friendly advice ."

John
"Have had mapped diesels for years but this is a first with a box (a Synergy 2t, Ron) and digibooster. It brings the car up to as it should be. Before the Avensis was a slug now there is decent power. Gains are a good 25% I reckon. Pre boost was where it was needed and now that's sorted. Keeping an eye on mpg but all in all happy days. Thank you Ron for all your help."
