Welcome to the forums, enjoy the ride!
So will you be doing retrofit HIDs for it? Only seen one so far.

But I am sure I can have my dealer address the issue.

Not sure if you are familiar, but the LNF motor has a torque sensitive learning feature. Since you have the GM Stage I, it is set ti accept a certain amount of torque. Because the air in Wilmington is more dense than that of Michigan, the computer has re-calibrated the tune to provide less boost.

You are making the same power you did in Michigan, but it takes less boost to get there.

Let me know if this makes sense, i don't know of your average tech will know that. :)
