It’s been cold, so I haven’t used the meth kit yet. That’s probably going to change the characteristics at the top end as well.

A lighter flywheel reduces torque which is very important when trying to get an X5 moving. The engine will rev faster but that doesn't help performance except maybe at close to redline. Even going quicker are high RPMs won't offset loss at low end.
