My ProBoost MBC was rock solid but I never ran it near 30PSI like you did. Sounds like your on the stock turbo so why not just yank the line and let it run wide open? Curious if that WG caused any of that given you had the MBC WIDE open. That's way too much boost for methanol for my taste but you have more experience with it than I do. Did you have to pull timing to get that boost?
Anyhow, if that's about average then I am curious why the STi did lower than expectations? Most (I think all actually?) Mustangs notoriously read low. We all know that but that's very extreme if that dyno has no setup/operator problems.
Also, interesting the AFR issues with the flashed ECU. One of the very reasons why I will never go with any flashed ECU. Why didn't you know it had WOT issues before you spent all that time and money going to the dyno?
I dunno...
