If someone wanted to do so on one of our systems, it wouldn't be very
difficult at all. It's definitely not necessary in any way for normal use as
our systems are quite efficient right out of the box.

Yes that is correct. But it helps a lot in street / drag / 1/2 mile / 1 mile events you want a low IAT at WOT so timing is not pulled due to knock activity.
