Trial ans error...

and testing and tuning will tell what your engine will do..

Most peeps are taking away 2-4 %

With a full pcv/autotune setup on a stock sled last summer using an AFR and EGT, I could go down 5% with no issues with non-eth 91 octane unleaded. At 9% it wasn't havin' any fun. If you gear down too far and overrev to 8600 or so, it will probably fall on its face at about 600 feet. YMMV.
