What is more, we give you control of where the increase is by providing the 5 or 10 settings adjusted on the box using the rotary switch. So if you simply want more low down torque and are not bothered about what happens over 3000 rpm, you can have it, or if you want better high rev performance for a more 'sporty' drive you can choose this, or like me, you want it all everywhere, just use the highest settings. See note below
Our Synergy 1, 2A and 2B also feature on/off switch(es) so you can disable the unit without having to disconnect it and a socket for the optional remote switches.
We were first to offer a 3-position dash switch to give you a choice of 3 settings while driving. This also means you get two tuning boxes in one - effectively a 'green' eco one, and a 'red' sport one at the flick of the dash switch. Other companies make you choose before you buy! Especially popular with 4x4 and tow car owners since they can switch to a higher setting only when needed and then benefit from improved economy the rest of the time. Now also available in illuminated push button version (sport or eco buttons).
