It's a speed $500 will be the price point. I can't see os going cheap. But less power is it worth the extra 2-3 mins over the stock speed? Now if it ran 15 mins I would say yes but idk. Depends on the main length at 20 mins it doesn't help but at 25 min main it might then on a 30 min main you still need to pit 3x like a speed 21 so where's the gain??
