Default Ram Cummins 6.7L High Output package

Since the introduction of the high output package for the Cummins 6.7L engine in our beloved Ram 2500 and 3500 trucks earlier this year which boost Torque to 800 FTLBS while still putting out only 350 HP (650 FTLBS otherwise), I've been curious bout the details.

What I've found out is they've upped the torque through a recalibration of the ECM and couple the engine to the transmission through a new converter. In order to help the 68RFe transmission deal with this larger load it now implements an ATF to water cooler.

The next thing they've done is added a Max Tow Package which gives the 3500 4x4 a towing capacity of 29,000 LBS. The upgrades include a stronger 4:10 AAM 1150 rear axle with larger bearings and stronger Limited Slip Differential or LSD. They've even added a cast aluminum differential cover that's said to reduce the gear lube temperature by 20 to 30 degrees. (Hell we've been doing that for years!)
The last thing the Max Tow Package includes is a larger power steering cooler.

The sad thing is that even with all these improvements the Cummins still lags behind the Sierra in performance and both the Ford and Sierra in MPG.

Thoughts?

Default Updates to Dodge

I have been looking at the 2012 models. Squid, you are right, Dodge has updated a lot of things but they forgot to increase the load capacity. Both Ford and Chevy/GMC have increased the load capacity by large amounts. To obtain the same load capacity in the Dodge, you have to buy the Chassis cab or the 4500 model --if you can find it.
I suspect I will go back to Chevy when I replace the Dodge 2500 Quad Cab I currently have. One of the car dealers keeps telling me they really want to buy my Dodge. If they gave me the NADA book, I would get about $38,000. Of course, I would have to spend $55,000 to buy a new truck equipped the way I want it.

the chevy duramax engine is built by isuzu i think?i would think that isuzu parts would be extremely exspensive!benz diesel engines are good but have the same problem.i built a 6 cyl in 1987 and the pan and front cover gaskets were over 600.00!just food for thought when shopping brands!

When I look at the torque curves for the standard vrs. the HO, I not sure I see an improvement. Looks like a toss up to me as to if there is any improvement.

If you look at the HP curve the HO engine has a bit more HP from around 1600 to about 2600 rpm, but the peak HP is still the same. I think the HO gains a peak 23HP at about 2300 rpm over the standard. So the mid rpm's you gain torque plus HP.
