When did the cummins go from 600 to 610 ft.lbs of torque? What month exactly?

 

Don't know....but was wondering if you could even tell a difference in 10 lbs of tq? Also has anyone dynoed one of the 325\610 motors what do they put out rearwheel hp.

 

What would you do if you knew an "exact" month?

 

2005 Cummins were suppose to be 610 torque rated. I did see early 2005 Cummins with the 600 rating. But most 2005s and up are 610 rated. Probably tweaked a couple of fuel map parameters just like the performance boxes or downloaders. But 10 pounds of torque would be hard to measure at the rear wheels on a dyno. All marketing, it was a "mine has more power than yours" thing.

 

Where is the tq rating? All I can find on mine is a HP rating.

 

Not that it matters, but I did notice that. HOWEVER- I can tell you that 20diesel HP & 45-55lbs. of tourque makes a H--l of a difference!!

 

mine changed from 600 to 610 when I did the flash what month was it? don't remember.

Mine too

I think it was in August of 04 or so when they came out with the 05's and made that minor change in the computer as a marketing thing against the Duramax engine when they marketed 605 ft lbs tq.

Dodge wanted to stay ahead of Chevy, so they made a minor tweak and called it 610.

If you have an 04.5 truck and get it reflashed...supposedly it is the same program.

 

Prob August of 04 or so when they came out with the 05 trucks.

 

Thanks guys!

Just woundering what my 05 was.

 

They are all 610's.

It was totally marketing. Cummins was delivering engines "centered" on 610 already ( to avoid low power complaints). There is no cal change whatsoever.

Centered is a term used to describe the average torque output of a batch/run of engines (like a tolerence, +/- 5 ft-lbs or whatever).
