Default 1999 5.9L (gas) - No power under 3500 rpm's

So, as the title states, I have a 1999 Dodge Ram quad cab 4x4 sport. When I am getting on a highway, or leaving a stoplight on a road where the speed limit is 55mph, it takes forever to get up to 30-35mph. Basically what happens is no matter how far I press the gas pedal down, it slowly increases speed. Once I hit about 3500 rpms, it takes off like a whole different truck. 3500 through 5000 rpms, it has power to spare. The only other real symptom is that when I do the above and the engine is cold (running for less than a minute or two when leaving work) the truck seems to "really bog" until I let my foot off the gas for second. It never shudders or stalls or anything though. It is wasnt a cable driven throttle body, I would almost think the truck just wasnt getting the throttle I was giving it untill 3500 rpms. There is a hill that I go up (about 25-30 degrees up) and from a stop at the bottom, I cannot get past 2500-3000 rpms, unless I mash the gas pedal and make it down shift to or (stay in) 1st.

It does have a slight shake at idle, nothing more than what I would consider normal though, I mean, it's not new, and it aint a cadilac. Also, once the engine is warmed up, the oil psi is around 60'ish while driving, but will drop to just under 40 at idle. It has never dropped below about 30-35 though.

I replaced the transmission and torque converter late last year because of some noise, but this problem has been there since before that.

I just picked up a triple pillar pod along with Trans Temp, Fuel Pressure, and Vacuum gagues which I will hopefully have in this weekend.

I am thinking it may be the fuel filter, but I don't want to drop the tank and everything if I don't have to.

I hope you find the solution to your problem. I have the exact truck, so I'll be watching this thread.
