My first attempts were only a tiny bit off. I think these will be good.

I like those maps....
Not a fan of the 40 degree exhaust timing at low load, other than that they look really good....
With a supercharger I think intake maps are the same as N/A, but you need more exhaust cam and a wider lobe centers... So your exhaust maps may be different than a N/A or turbo...
On N/A V8s we ran 106-108 lobe centers...

For best performance with a blower, you should look for a cam that has higher lift and longer duration on the exhaust side. Street performance with a blown engine is usually best with a cam that is ground with a 112- to 114-degree lobe separation. With the use of an aftermarket camshaft, follow the camshaft manufacturer’s recommendations for valve springs. Blower cams can typically be run “straight up.” Note that a blower has tendency to lessen the rough idle of radical cams."
