   For some reason my VTS keeps running rich and has a poor milage. I see back smoke on high revs and the exhaust is smeered in black.
   
   I replaced the GREEN temp sensor for the ECU, Cleaned my K&N, Changed Spark plugs, Lowered the pressure on the FSE Fuel Boost (3bar)....anything else?
   
   I am running a VTS with a Ram Air induction kit, w/ FSE boost valve, Supersprint system (no cat but this was not a problem beore).
   
   Ideas?

   It sounds like your fuel map could have a fault on it. If you take it in to citreon and get your car put on the diagnostic machine and that will tell you any probs you have with your ecu, its not cheap but is worth it to sort your car out.

   I have disconected the batery overnight to bring the ECU to defaults but nothing changed. I'll try the ungodly creatures at the Citroen shop on Monday.
   
   Thanks!
