Is this your first time to lower altitude since your tune?

That sounds like wastegate spring boost which I think means solenoid or the ECU not in control of it.

CEL? Flashing cruise? Any codes?

Forget the leak idea I think. The solenoid bleeds vacuum, so a vacuum leak would cause over boost if I am remembering correctly.
