Pistons, Dynamic CR + 91 octane =???
You want to avoid that whenever possible, it rarely pays off VS CR.
(it does however in the power adder world)
That's something Ed Wright and I discussed prior to my 355 and 383 builds.
(which saved me from making what could have been disastrous decisions with my build choices)
I run 43* at part throttle and 36 at WOT. Pretty typical for an N/A car.
My point was that if you want to push the envelope on CR, enlist a tuner with a solid reputation.
They'll make sure your tune is optimized.
