To chip it or flash it?

[wobblyboot]

I am interested in getting more power and economy from my 2005 WH V6 CRD.
Is having the chip flashed the way to go, or do I replace it. (if so, what brand is best)
cheers

Definitely flash it.

Do a search here on AusJeep for "Green Diesel Engineering" or "GDE" to find out more info.

Thanks guys

Definitely go Green Diesel Engineering ECU reprogram. You buy them through Murchinson Products as Clarky mentioned. Awesome chip with heaps of extras and they can do custom programs such as DPF deletes too.

Is there a chip or flash for the 4.7 petrol that is worth doing?

The only one I know of that people seem to have any success with is the Superchips Flashpaq 3785: http:// http://www.jeepgarage.org/f1...nfo-34215.html

The Diablosport tuner which is popular with the 5.7L Hemi owners (I think from memory it also allows you to adjust shift points and rev limiter better than the SC tuner) is apparently not supported for the Jeep 4.7L, but is for the Dodge Ram etc: http:// https://www.diablosport.com/...33351&start=15

I also thought I had read that you can use a Hypertech tuner on the 4.7L, but according to this thread it is not supported either:

I think Briteway would be a good person to ask as he has done all the research and used to run a 4.7L WJ.

Provided you are realistic with your expected performance/economy gains the Superchips tuner should be worth it. Coupled with the Transgo shift kit and a decent free-flowing exhaust system you should see good improvements in both.
