Chrysler 300c CRD Engine Tuning and Performance

Whether you’re looking for more performance or economy from your Chrysler 300c we have just the tuning package for you.

Developed by experts in the field of engine re mapping we are pleased to offer our exclusive tuning packages which will transform the drive ability and performance of your Chrysler 300c.

No ordinary re map... Instead of a ‘one off’ tune our package gives you the flexibility to swap between performance and economy maps simply and quickly via a switch box. Just plug the box into your OBD port and in a few minutes your 300c is ‘sipping fuel’ in economy mode or transformed into ‘2 ton animal’.

Performance figures and fuel economy gain information are offered as a guide and subject to vehicle condition/usage, as such we can offer no guarantees that facts and figures as indicated above shall be attained in all cases.

Fitted to most modern Diesels a DPF (Diesel Particulate Filter) is a component trapping and periodically burning off matter found within exhaust gases. The EGR Valve (Exhaust Gas Re Circulation Valve) re directs some exhaust gases back into the engine cylinders to replace what would be oxygen to be re burnt. Both components do assist to reduce emissions but both also do have an impact on performance and efficiency.

Our Stormtech+ remap package addresses both these issues by including both DPF and EGR delete software modifications allowing for an error free removal of the DPF and deletion of the EGR Valve operation which does not need to be removed or unplugged. Both modifications are tested as fault code free.

CAUTION: The Stormtech+ remap package must only be used when removing the DPF (e.g. using our DPF replacement component) and should not be used when a DPF is in situ.
