The ML has two 3.0L variants;
1] 300 Cdi Blue Efficiency
2] 350 Cdi. Blue Efficiency
3] 350 Cdi
The original 3.0L had 510 NM of torque as standard and this applies to 2005 and on CRD Jeep GC's.
The new MB 350 Cdi is the old engine with a very mild increase in power output. For 2010 it is rated at 224 HP and the 300 Cdi is 190 HP.
The highest power rating without blue efficiency is 230 HP.
I am not sure where you got your 250 Hp from.........
The MB ML always had a different air intake from the WK / WH hence the small power differential.
The official upgrade was a Startech by Brabus chip which increased power to 258 HP but that mapping had fail-safe's including rev limiting to 3000 rpm with the engine cold and power lowering at high temperatures.
Most basic mappings only give a power hike with no consideration / protection to engine life.
I am sure you can squeeze 300 HP out of this engine and damage it but why do it when a 5.7 hemi will give you more performance for the same money if that is what you want. Due to the gearing and rpm engine range you will only reduce the 0-60 by 0.5 seconds and increase the top speed by around 4 mph. Top speed tends to be irrelevant due to speed limits and ATR tyre speed rating limitations.
I have driven an upgraded CRD and barely noticed any difference.
I bet you that a stock CRD engine that has been run in properly and looked after will give you the same perfomance as a chipped engine that has been thrashed and badly run in, if not better.
The CRD can haul 3.5 T, it can do up to 31Mpg Avg and will perform on par with a 4.7 V8 gasser. Its great off road and has enough torque to put a lot of V8's to shame. If you want performance look at the 5.7 Hemi or SRT8.
