threedogs, I think you have a problem with your gauge mate, I would check that as it doesn't sound right.Originally Posted by threedogs
The CRD engines have a much more advanced engine control system so NADS are not necessary unlike the Di's but a few people still put them in.
Blocking your EGR will help reduce the soot build up( but can create engine errors) and a catch can will reduce the blow-by going back into your intake.
ECU controls the boost very well so dowes and needle valve are not necessary.
EGT and Boost gauges are handy as they tell you how things are in the engine. Normal egt temps will be up to around 550deg C in a CRD engine as they run hotter compared to the Di's. I only get there when towing or flogging it uphill.
Personally I have just put the gauges in and nothing else. Better off spending your money on a good hi flowing exhaust
