Stock intake VANOS looks completely fine to me. You may consider retarding the first 5-7 columns a little bit to stabilize lean burn. I would set the first column to 120 down to 3500rpm and then gradually drop it to 112.5.

Exhaust I think you have the right idea, though I don't understand that little 100.12 island. I would keep the last 3-4 columns stock, and basically shrink that blue/purple island towards the right since you don't need the exhaust dilution to reduce your pumping losses anymore. At medium load, a little bit of overlap is helpful for raising charge temperature and combustion speed. E.g. at 2500rpm, I would set that row to something like 105 105 105 102 100 97 94 92 90 90 92 95.
