Thunderstroke 111 failure!

I have a 2018 RM ICON, aftermarket AC, true duals with rush warhorse, lloydz 558 cams and PVCX tune. Purchased late April. I rode it pretty much to the T during the break-in up to 500 miles. At that point I've not babied it at all, actually did the remoter tuning and ran the hell out of it. Spent a lot of time in the 4K to upper 5k rpm range during running logs for tuning.

At 4300 miles so far and NO problems.

How do you like the 558 cams? I am considering these myself. Does the mileage drop much? how is the bottom end say 1500 to 2200 rpm?
Bottom end is good, I hardly spend anytime below 1800rpm. Motor pulls strong from idle all through the rpm range, the only flat area i've found so far is right at 3800rpm, but its hardly noticeable. As far as bang for the buck, I am happy, happy, happy as Si says. I actually purchased the cams from a friend that went with the 116 kit, he only had 1800 miles on them before the swap.
