We offer several Custom Remapping options for both petrol and diesel vehicles. We can offer economy tunes through to performance tunes, or something bespoke for vehicles with hardware modifications.



DPF & EGR Solutions

Are You Experiencing DPF Problems??


   Are you having problems with your DPF?

   DPF or Anti-Pollution warning lights on your dash?

   Car in “limp home” safety mode?

   Poor acceleration and MPG?

   Facing expensive repair costs to replace the DPF?

   Confused what the best solution is for you?

How Can JCS Help With A Blocked DPF?

One-off treatment for blocked DPFs


TUNAP DPF CLEAN is a professional workshop treatment designed to clean Diesel Particulate Filters that have become blocked due to a build-up of soot. It is a much cheaper solution than replacing the DPF.


This treatment will include a direct flush into the DPF followed by a diagnostic regeneration of the DPF to reset the engine management system and finally a test drive 


If, on one of those very rare occasions, it fails to clear the filter we will need to look at other solutions for repair. This work will need to be quoted for individually as all vehicles will vary in the length of time this will take.



Regular preventative treatment


Our DPF Maintenance Clean is a professional workshop treatment designed to be used every 6 months to prevent the build-up of soot in the DPF.  


This product is designed with unsuitable driving conditions in mind, mainly short distance driving and lots of town driving with stop/starts. These conditions are major factors in DPF filter failure, as the filter never gets up to the correct temperature to self regenerate. With our proven PARTICLE FILTER SYSTEM REGENERATION ASSIST ADDITIVE you can be sure that you are keeping your DPF healthy.




Book in today and have the peace of mind knowing your DPF 

is being kept clean, potentially saving you hundreds of pounds.

This is a 'drive IN - drive OUT' service . A vehicle delivered to us is subjected to our standard DPF Service protocol:
