I was just wondering what the difference in fuel timing is between the stock ecu vs 91oct apr chipped ecu vs 100oct race apr chipped ecu? Or does the APR chip mostly focus on Boost increase? I mean how much is the fuel timing really changed?

i actually run about 1-2 psi LESS of boost when on 100 octane.

probably only the person who made the timing coding can answer that, but I can san that it is significant enough that a)there is a noticable difference and b)the 100 octane coding won't work well with less than 100 octane fuel, and the other programs won't be nearly as good with 100 ocatane fuel as the 100 ocatane program.
