Torque curves on 6.4 hemi

I know, this is a diesel forum. But I know there are some Ram insiders here and wondered if anyone knows how quick the torque comes up on the 6.4 hemi. It is suppose to be re-done for the 2500 and towing. I had a 5.7 hemi before the 5.9 and the hemi kind a sucked at towing due to the lack of low and mid-range torque. The 4.10's put the tow rating up there a bit and if prices and smog stuff on the 6.7 continue, well I know I am not alone in jumping ship.

2014 White Laramie 2500 CCSB 4x4, 6.7, Keyless go, buckets, Romik steps, Michelin Defender 295-70-18 tires, Snugtop Supersport. Big spoiled Bernese Mtn dog in the back seat. Wind River 250RDSW bumper pull TT (31ft, 7K LBS.) 2003 2500 4x4 5.9 best ever, SOLD.

From what Ive read it will reach the same amount of torque the 5.7 puts out only 1000 RPM sooner. If you google 2014 ram hd 6.4 hemi lots of good reading pops up.
