   I don't know. How would i be able to find out if it is? Im think off getting bigger injectors uprated fuel pump and a slandalone ecu and removing the 5th injecter as i was told this will make the car run sweeter and make 230bhp but this is @ the cost of £1500 lol. The turbo kit i have was 3k from cituning and give 197bhp so i dont wanna be forking out at the mo.

   Sorry just looked though my paperwork and it must have a Sig Con as this was brought with the mf2 fuel controller.

   Are you using new fuel or you using 4 year old fuel?

   As above petrol goes off after 3 months ish, and. Leaves a sticky yellow coating on everything.
   
   Drain the old and fill with new fuel and it will clean itself eventualy.
   
   You couldn't help me out and note down where all the wires go to from your 5th injector and sigcon could you ? I'm having problems on wiring mine up cheers

   get the mf2 set-up properly with a maps sen--so fuel is added as a function of boost /manifold pressure
   should be no fuel from fifth injector when not on boost
   disconect it and try it ,keeping off boost
   if it cleans up theres your answer
