    I'd like to snoop through some logs, who has some?

    Must be nice to have 93. We have acn91 aka 88-89.
  3. Yeah it really is. I couldn't imagine having to use 89! I feel for you brother.

    Stock Turbo (N55 PWG) with E30 custom tune:

    Tuned by @TwistedTuning

    We have since added several degrees of timing. Fueling is a limiting factor right now. I will be adding a Stage 1 LPFP, increasing E30 content to ~E50, and adding more timing since the higher octane should support it.

    Car just put down 364/497? with the dyno operator bogging the crap out of it and causing a huge throttle closure/dip in rail pressure. I'll be back to the dyno with latest revision soon to see what it puts down with some cleaner pulls! Hoping for 380whp/500wtq. Can't see why the additional timing across the board wouldn't get me there...

    EDIT: I am disappointed to say that the stage 1 LPFP didn't help my dip in rail pressure. After installing the pump rail pressure stayed the same. I did reset adaptions though and things improved, but I don't think the two are related.
