On my sub setting it placed it at +10, I had to tone it down a bit but maybe that's a matter of preference. From what my ears tell me I have a much more balanced surround sound after my adjustments were made. Before the adjustments I had a dead spot between the fronts and side surrounds now it feels much more filled in. I really do appreciate the advice though amigo. I'll try it again tonight just to make sure.

That's either a sign of some incredible boundary reinforcement or bad readings on the part of the mic (or its in a very weird position as far as bass goes). How much did you change the distance? Where did you settle on crossovers (& what options does the receiver provide)?
As far as the +10, I would try to turn the gain on the sub itself up and rerun the calibration (and then adjust as needed afterwards) to keep the sub trim at or below 0. This is just to prevent the signal from clipping.
Edit: also, make sure the mic is at least two feet from any walls. If the mic is within two feet of a wall, it may be getting bad readings.

The mic was off by about 2 or three feet. I think what's happening is my speakers are against walls which is causing some odd readings to occur. I'm so limited on space in my room but was able to bring them around 6 inches away from the wall and I have since placed a few dampening tiles behind them which helped some. My crossover is set at 80hz for my center and fronts, my surrounds are set at 90hz. So when I calibrated my sub I have the volume at half power, your saying I should raise the volume up more until the mic sets it around 0? What is clipping? Thanks for the pointers mate.
What AVR are you using? I ask because +10 on the sub trim may be the upper limit...if that is the case, you don't know if the AVR wanted to set it higher (say, +15 or +20).
Regardless, I would follow dkfan's advice and recalibrate until you get a sub trim in hte negative numbers. -8dB to -6dB is ideal as it leaves you plenty of room to bump up the sub trim without going over 0dB.
If you happen to have an AVR with Audyssey, here is my quick-n-dirty sub setup procedure (even if you don't have Audyssey, most of this still applies):
Set the gain on the sub to around 12:00-2:00 (just a starting point, gain structure can vary greatly from one manufacturer to another). Set phase to "0".
1. Connect sub and place it at the MLP
2. Do the sub crawl to determine the best location
3. Place sub in that location
4. Run Audyssey, first mic position only and "calculate"
5. Look to see where Audyssey has set your sub trim, you want it to be around -6db to -8db ideally
6. Adjust the gain on the sub up or down as needed
7. Repeat 4-6 until you get the sub trim around -6db to -8db
8. Run the full Audyssey calibration
9. Bump up the sub trim by 3db to 6db to your preference
