Crank pulley is pinned, and I run 93 when I can get it. You would have to ask my tuner Ed Hutchings at Hi Tech tuning, but he said the tune was very conservative and could take a lot more. I do plan on adding an Alky Control meth kit with dual nozzles. I'll use it mostly for the piece of mind for the octane boost, but will have Ed retune it. The guys at ECS make a lot more power with stock LS3's, but they always run meth for protection. To answer your question, Ed is one of the tuners for HP Tuners and if he says it's safe, it's safe.
