Mercedes’ BlueEFFICIENCY engines offer a good compromise between acceptable performance and great fuel economy. But if you squeeze them you might be able to get more power. That’s what Superchips UK has done with their new ECU map for the Mercedes’ Bosch EDC17 ECU which increases the power and torque while promising noticeable fuel economy improvements.

This kit can be fitted to C / E / M / R and S-Class models equipped with the 350 CDi BlueEFFICIENCY engine and will deliver an extra 34 bhp / 80Nm ( up to 284 hp and 642 Nm at just 2469 rpm). That results in a sharper, more exciting, more responsive driving experience.

As usual Superchips kits are well-priced and come with 12 month / 30,000 mile warranty. This package costs £445.00 including installation and VAT.
