Engine and trans tune order ?

I just Femto unlocked and installed an OTS stage 1 multimap tune. Do I need to reflash the XHP I had flashed prior?

Believe there are separate hardware modules:
TCM - xHP
ECM - Femto unlocked.

They are separate so no need to reflash XHP. Congrats on the unlock and getting some real power. This car is so much fun!
