Does the 735lbs of torque make a noticeable difference and how much weight are you towing ?

Yes. And it's 800lbs. Torque is what you need from the get go.

When the 2011s first came out they were rated at 735tq. Then the Duramax came out at 765tq. So ford increased the tq rating to 800 later in 2011. Now all 2011 and 2012s are 800tq.

Mine had already been updated when I bought it but the huge torque that these trucks put to the rear axle is very noticeable as compared to older 4 speed or 5 speed automatics. The new Ford is capable of putting 11,000 ft lbs of torque to the rear axle when in 1st gear. My old '04 Cummins was able to put about 5000 ft lbs to the rear axle.

I can't imagine upgrading for that reason unless you are having a problem pulling with your F250. There were a lot of other changes made at the same model year tho.

If you were to install a Spartan or H&S tuner you would have allot more power than what the new ones put out. And likely get better fuel economy as well.

SRW long box with 800lbs feet of torque with 9000lbs on the "bumper" hitch (nothing else loaded in the bed mind you) means I have to be careful when starting from a dead stop to not spin the rear tires in certain situations even on dry pavement. OEM 18" Michelins.
That load has also never slowed me down while ascending hills/mountains of reasonable grades. I could have always gone faster, above 65mph, but there is no reason for me to go any faster.
I love me some land yachting

Actually a very good question in my book: how much "seat of the pants" difference between 650tq & 800tq...interesting...
I'd think empty you'd notice little, but the heavier you're towing the more those extra 150ft-lb would come into play...
Would be fun to drive a late 90s-early 2000s diesel with ~500ft-lb, then a mid-2000s with ~600-650ft-lb, then one of the newer ~800ft-lb monsters towing the same heavy trailer, over the same 15-mile stretch of mountains, to see just how much difference there'd be.
My guess: something like my 02 7.3L, with 505ft-lb, maybe 40-45mph up the mountain, the 600/650ft-lb class maybe 50-53mph, the newer 800ft-lb'ers maybe 60-62mph.
Of course newer 6-speed autos vs. 5-speeds & of course the older 4-speeds make this an unfair fight, but it's still fun to speculate on.
