Helix DSP tuning help

Hi everyone,

I have installed my helix dsp mini and have been playing with the tuning of my car for about 2 weeks now.  I am using a pioneer 80prs in standard mode with single rca from front outs to the helix.  I had my system near perfect in network mode but I am upgrading my headunit to a touch screen with hires playback(mostly because a botched Bluetooth update so no bluetooth) soon so I put in a dsp.

1. I am having trouble taming the tweeters. the input sensitivity is all the way down on the helix and I had to turn the gain on the amp to the lowest with about -7 to -10 decibles in the software to somewhat match the mids.
   
2. I am having trouble getting the imaging I would like. the music and vocals all sound like they are coming from the far right of the passenger dash and I cant seem to move it.  I did all my measurements in inches with a tape measure to the headrest. Should I change these numbers?  I have been trying to level match the left and right for the last 3 days but sound just ends up off.(im not sure if I was using rew correctly)
   
3. I am on here for some help in these areas because my ears are getting fatigued(especially the left one) and during my silence break maybe someone could give me some insight before I go back at it. Let me know if I need to add any more info.
   

Here is my setupics are of the software
