Cam companies have their reasons for establishing certain lashes for certain lobe profiles. We don't know why,but they do. And they are not going to do anything to make their cams make LESS power. That's their reputation on the line. You can loosen lash for less duration in the hopes for more bottom end power. Or tighten it up for more duration like stated before,for topend.But the effects are usually minimal,especially for the risk you are taking. Why did they specify that particular lash????....who knows,just go by it and you'll have one less worry.

But you asked "why" they were different,not if you can change the lash. Looser lash cams typically have a more aggressive lobe profile.Like faster opening ramps.
