I like the speed calculators. When combined with the info from a data logger, it makes tuning much easier. I wish Castle would fix the new XLX. Their data logger is pretty awesome.
Yeah, the diff ratios don't make a HUGE difference, but there is a mechanical advantage there that results in a little more power at the wheels.
Looks like there is a ROSSA event planned for September just North of LA. Can't wait for that.
