SOURCE: Not enough hot water
Some higher end models do have an adjustment that is behind the face plate. You would have to remove the handle and the screws in the faceplate to expose them. If you have adjustments they will be located on the brass valve body facing you. You will need a flashlight and a flathead screwdriver to make the adjustment. If your model is not equipped with adjustments you could have a faulty valve stem. The stem is comprised of a rubber band like gasket that separates port holes into which the waters flow. There could be some piece of trash blocking the port not allowing adequate water from the hot side into the valve.Some valves stems are also able to be installed upside down causing the same issue as the ports do not rotate fully to allow adequate supply. However you say that you have adequate pressure on the hot side but not warm enough. There is another possibility also based on the way the shower supply was plumbed but there is no need to go into this unless this does not resolve your issue. I hope this is of assistance and thanks for using Fix Ya. Please let me know if I can be of further assistance.

I found a way to get warm water in the shower, but I'm not sure it qualifies as a solution. After trying everything else I thought that maybe when I was feathering the faucet in the shower toward the cold side so I would get warm water that at a certain point it blocked the flow on the hot water side enough so that the sensor in the hot water heater sensed there was no demand in the line and it shut the water heater off. To test this, I went to the kitchen and turned the kitchen sink faucet all the way to the hot side and then turned it on so that I got a small flow of water. I waited for the water to get hot to be sure the hot water heater was working. Once it was hot, I left it running to keep demand in the line and then I went to the shower and turned the faucet on. When the water got hot I started feathering the control towards the cold side and soon I had warm water. So I think I'm right in that the sensor in the hot water heater was shutting the water heater off when the demand in the shower was lowered to a certain point when I was trying to adjust the water temp in the shower.
So now I can get warm water, but it means I have to leave the hot water running at another fixture in the house to create a false demand in the system so the hot water heater doesn't shut down. Is there a way to adjust the senor in the hot water heater so that it will stay on when I'm using the shower only, so I don't have to waste water by running another faucet when I want to take a shower?

SOURCE: Water Temp not hot in shower
you need an allen key to remove the handle once the handle is removed than you need to turn the grey plastic temp guide counter clockwise as far as possible

Yes, I believe this unit uses a cartridge right? They do fit a little tight due to the small washers on the back side of the cartridge. If this is the one I'm thinking of, there are two leg like appendenges that come off the back and fit into small holes at the back of the manifold or what some call mixing valve housing.
