MightyMike 5 signal bars fluctuating

[TouchProPro]

I just flashed my Sprint touch pro with MightyMike 5 and it is pretty stable except for some random lost data connections while using IE or Opera indoors. I notice that I have 1 or 0 bars in my house but still get some internet connectivity and calls are as reliable as the standard 6.1 ROM.

What's odd is that when I call somebody or launch an application that requires data connection, the bars flash to 3 or 4 and then disappear completely. This leads me to be suspicious of the true signal strength. When I walk outside I should get at least 3 bars. It remains at 0 or 1 bar when I stand outside for 5 minutes. I know that's not right.

This is my first use of a 6.5 ROM so this may not even be a MightyMike5 problem.
