• IMPROVES FUEL CONSUMPTION when you aren't using the extra performance.*

TECH INFO:

The Synergy 4, uses 3 chips, one of which is a state of the art microcontroller making this a genuinely digital product. It uses 2 channels - one processes the MAP signal (unlike rival products - even those costing 3 times the price that only use the map signal to turn their box on and off) and the other controls the fuelling.

The controls enables you choose where the extra performance starts and how much performance boost is available.

Fitting is straightforward - it is part plug in to the map sensor and just 2 wires to connect to the injection pump wiring in the back of the ecu plug. Full instructions are supplied and no wiring mods are needed so the vehicle can be returned to standard at any time in seconds, with no tools being needed.  There is no reprogramming of the engine ecu needed either.

^No specific claims or guarantees of power or torque increase are made as the results depend upon the make & model of vehicle and engine condition. * No specific economy improvements are claimed since there are too many factors outside our control such as vehicle condition, how and where you drive etc.

IMPORTANT: PLEASE LET US KNOW WHETHER YOUR INJECTION PUMP HAS AN 8 OR 10PIN CONNECTOR

CUSTOMER FEEDBACK:

"Ron fitted one to my 1999 VW Autosleeper Clubman 2.5tdi 102bhp and I cannot believe the difference. The performance used to be okay above 2000rpm (55mph) and then it 'died' on hills if the revs dropped below 1800, meaning quite a lot of gearchanging, not helped by the big gap between gears. Not any more - I have power a plenty from 1500rpm, so most hills don't require to drop a gear AND fuel consumption is better by about 10% on runs. BEST £80 I'VE SPENT ON ANY VEHICLE!"
