Sig,
Since you are getting new limbs...
When you/the dealer take the bow apart, measure the string and cables and make sure they are the correct length.
If not I would
A) contact BT and have them get you the correct lengths
and
B) for a quick fix since you need it for the shoot, you can likely take some twists out of the cables to where the harness is not so wound up and then put twists in the string to get the draw length right.
Please let me know how you make out
P.S. Don't be a stranger Kevin!
