Joshj had this one in his crd he will be able to let you know all i can say is my 4.8 had to go big to try and stay with him when we drove back from the river trip ....the chip has a harness that just plugs out when it has to go for service ...
IMHO ....put a full madman always good to know what your watertemp boost ect is and it has a audioblie alarm when things are not correct :salute:

Keith, I think you may have misunderstood.

The Madman and the chip are not related. A madman is an engine monitoring system. It monitors up to (i think) five critical engine factors, depending on what sensors you have fitted. For example, EGT, oil pressure, oil level, water temp, water level. It gives early warning if something goes wrong that can damage your engine. It also gives an audible warning if a value goes over a user set-point.

In my opinion, every engine probably should have something like this, particularly every tubocharged engine. And this becomes even more important if you have made any modifications, especially to the management system.

Hi Keith. The 3.0CRD is very slugish in standard form. I fitted my madman system before I did anything else. The norm is to not exceed 650degrees C. And I can tel you without towing anything it does get to 650degrees C when driven hard. I do think that the newer 3.0 can handle higher temps. But I played it safe and kept mine under 650.

The chip and 3" freeflow make an enormous difference in drivability. Also on open roads when heavy loaded for overtaking. A Dastek chip is the only safe way to go. And it must be tuned at a good tuner that understands the dangers of a diesel.

Feul with std tyres and no extras is easy 9km/l at moderate driving. Add 33" mud tyres and it goes to 7.5km/l. Add weight and you have a hard time getting to 7.5km/l. The end is a power to weight argument and weight always wins. So if you up your power after all the weight you can get over 8km/l. The low down torque of 380nm at 1500rpm and 440nm at 2000rpm will sure assist in towing.
If your tuner knows his stuff then you will have a hard time seeing 650degrees C after tuned and 3" freeflow. :mytwocents:
Being alive is a Blessing!!

Regards,
Joshua
