Looks good. 'Grats.
Just fyi your motor can easily take more boost even with 135k miles, but you probably already know that. I'm seeing fairly aggressive spark but very mild boost. I think more boost and less spark would actually be easier on the engine.
I am pretty sure I am running more aggressive timing than that on my car and I have seen others who have even more aggressive timing. Especially under 100kpa. Not that you are ever in that region on the track...
I don't want it to be risky for detonation if everything gets overheated at the track. Heat soak sets in to everything when the asphalt is 140+degrees and you are running as hard as you can in boost for 20-40 minutes straight. Everything was cooking and breaking at 8psi last summer.
