Default Early 2011 diesel upgrades to match late 2011/2012 performance specs

Hello, I am a newbie to this forum (I hope I'm posting correctly) and new to diesel ownership. I just purchasd a 2011 Ram 2500 diesel truck (only 3250 miles). It is an early 2011 so it is not designated as HO. I am getting conflicting information about the differences. A concensus of diesel mechanics I've talked to, say the ONLY difference is the programming. "Official" Chrysler documentation is not consistent on this matter either. One document says a higher rated torque converter is included in the HO another says there is a transmission "tweak" included in HO. I would like to know the straight scoop and if it is only programming, can I get a legitimate Chrysler approved (and CARB compliant) programming upgrade that won't jeopardize my warranty. An answer would be most appreciated. Thank you and glad to be a member of this community.

Just so you are aware, there are no chrysler approved programming options, you either go for an aftermarket programmer or you leave it stock. As for your warranty, it can not be voided unless the failure was caused by the modification, not just be present. But, in your case, with different programming they can look at your entire drivetrain and dent warranty claims... IF something fails.

Thanks Kurtis. I was afraid of this answer. I still would like to know what the true ONLY difference is that makes the performance specs different between the early 2011 and the HO. I think Chrysler could make money if they would "sell" an approved upgrade as opposed to customers spending their money on after market solutions. I would be willing to pay a fairly substantial sum for an approved/CARB legal reprogramming that wouldn't jeapordize my warranty.

Default Why doesn't Chrysler do this like Ford?!

For those of you who have already purchased a 2011 Super Duty diesel pickup, Ford will provide the power upgrades free of charge. Customers will get a letter in the mail explaining the 30 minute software adjustment procedure, which will be conducted at a dealership near them. 2011 Super Duty diesel pickups in dealer inventory will receive the upgrade as well.

In trying to answer my own question, I received this message directly from Ram. I hope this helps other with the same question ...

According to our records, your Ram 2500 was originally equipped from the
factory with the 6.7L I6 Cummins Turbo Diesel Engine (ETJ). The 6.7L
Cummins Diesel H.O. 800 ft lb torque increase is aquired via a software
programming change and a different torque converter is used in the
6-Speed 68RFE automatic transmission.

At this time, a software/programming upgrade is not an available option
for customers with the standard output 6.7L Cummins Diesel. No
additional information is currently available.

I also have a 11 2500
I am under the understanding that the HO is the turbo charger and they had to upgrade the torque converter to handle the 800 ftlbs of torque it produced

I thing Gerry K has answered his own question correctly, and I think fishndaflats is off the mark on this one.

Our trucks can easily be chipped up to the 800 foot pounds, but our tranny can't handle the torque.

OTOH, our 650 foot pounds is governed by our software, not limited by the engine's potential, which means we have the flattest torque curve out there. Small consolation, but that is a true measurable benefit from the strength of the engine, even without the 800 ft lb peak.
