That's about what I run. With the Hydra the first 30 seconds are even richer (11-11.5:1) with the post start enrichment. I think I stop adding any enrichment fuel at 70C, but if you car doesn't mind it at 51C, go for it. Currently I idle when warm at 14.5, but may tune up to 14.7 or higher at some point.
