I've wondered what a stock 45e has in the way of turbo boost? Is 1.3BAR? That seems high (I come with a longstanding thought that 12-15PSI is acceptable for LT reliability - below is better and Higher is riskier LT) considering the 45e has been detuned from the 40i given the extra E power.....I can't find good info on the details here for stock turbo boost?
