Yes. I got lucky and got in on the beta test. Right now I am running the regular gas flash and there is little difference between that and stock. With the premium fuel, there is a noticable difference, but it still doesn't address torque management, shift points, or the rev limiter. They did figure out how to raise the speed limiter.

I don't know if this applies but I have noticed this truck is one of the worst vehicles for drag when you let off the gas that I have even had. Even my Durango R/T with 392's didn't make you feel like you put the brakes on when you let off the gas on the highway is where I notice it not in the city. 60 mph down to 40 in a few seconds, then it mellows.

I've noticed (and read on other boards) that the '09 Ram 1500 is programmed to decelerate when shifting between 1st and 2nd gear. 
I guess it's a way to save fuel. Has anyone else noticed their trucking doing the same thing? Have you read or heard about having the ECM "flashed" or know of a programmer that can "correct" this?

In my 300C, my SRT8 and my CTS-V, plus recent other vehicles--an after market tune changes the vehicle dramatically.
I have noticed that-at least in my experience- Chrysler vehicles are detuned the most, and seem to be the least user friendly for the tuners to figure out. The SRT engineers have said as much in their on-line forum chats.
So when I drive my Ram, it is easily noticable and very frustrating. The vehicle is substantially de-tuned in a number of ways--most noticeably from a standing start under hard acceleration, and during shifts.
I can't wait for a good tuner (Hypertech, Diablo-whomever) to come out with a fix for this. This truck will ten feel like 390hp/407 TQ. As it is now--it feels significantly less than that.

I don't know about drag on this truck, but I noticed with mine (when not in Tow/Haul mode) when I let off the gas this thing loves to roll. I guess it's the torque converter not staying engaged. I feel like I use the brakes a lot on this truck to keep from running over cars in front of me.
