I believe it was something like 10hp increase per CR point...not sure off the top of my head, can anyone else verify?

+4hp
8hp for every point up
so your going half a point
so it should be abot 4-6hp

I thought it it was between a 4% and 6% increase. If you tuned it around the compression you'd see big gains
