What are you doing to get more low end.
Just got a 9k 5er and the 6.2 handles it ok as long as the revs are up around 4000 as it seems this engine loves to be cranked. What kind of add ons are making the low end of this truck a bit more useable. I know I should have got 430 rear but I have 373. Does 5star tunes wake this beast up earlier or what about cold air intake and a freer flowing muffler? Would like to know what everyone is doing and how its working for them. Thanks.

Intake and exhaust mods are for the most part a waste of money on modern vehicles, (IMHO) with the computer controling everything. A tune will help with the shifting and give you a bit more HP/Tq and is generally the best bang for your buck, but you may void your warranty. gears W/tune is your best course if you want to spend the bucks, BUT; having said all that, this engine makes it's hay up high in the RPM range, and that isn't going to change. You'll have to get used to it, and accept it. Won't hurt it a bit to let 'er run. Good luck.

You are correct. I do that sometimes with a load. For example, I just took a trip to Arkansas from Texas and got into some hilly roads with 5200-lbs on my flatbed(3.73) and locked out 6th gear.
It made all the difference. Once you learn how to play around with the gears, it's makes towing a load much easier.
Still, a 4.30 will jump off the line faster than a 3.73
My old F-550 with a 4.88 would sprint out of the hole fast.
However my 6.2 can too, but only if I STOMP on it

Not much you can do to gain torque. As mentioned...you can definitely use the "Manual" portion of the tranny to hold the gears longer. Or when running in "Auto"...lock out the higher 5th and 6th.
The real key here...is not to be intimidated with those high rpm's. That is how this engine is designed. It will run at 3500 thru 4500 rpm all day long with no worries.
Just saying...I am so glad that I ordered my SD with the 4.30's.

I have the 4.30 gears but my truck feels like it has 3.25 compared to my v10 with 4.10 gears. I added an intake and exhaust and it made a tiny improvement, not worth the cost. These engines just like to rev. Evening hauling an atv in the back makes me use the tow/haul mode on the tranny.

I think it comes down to how you want to tow and you need to know what to expect....... From what I have read people are buying the SD with the 6.2 and are expecting 6.7 performance.............
The 6.2 makes plenty of power to pull most all loads....your just not gonna do it as fast or as efficient as a diesel. They do make the power higher up and if you dont like that then maybe you should consider a different power train.
Most all gas engines current and older are going to make their peak power higher than any diesel that is just the nature of a gas engine. These 6.2's make just about the same power the diesel's did 8-10 years ago.
I think most people just associate a Super Duty to make all its power right now weather its a gasser or a diesel.
Bottom line is the 6.2 will pull what you wanna pull you just gotta get the revs up!

I tried the 87 economy tune for a 850 mile trip and saw a bit of difference in mileage then put the 87 perf/tow tune in it and I will not ever put the economy tune back in, the truck is that much better with the tow tune.
