87 = 91

91 = 95
93 = 98

Thanks. That is interesting, I guess there is not much to worry about then.

You could see some benefit from a tune. Timing is important with a hotter burn in you cylinder. Probably not a issue of damage but performance improvement to take advantage of a higher burn rate in combustion...

Good luck in your venue!
