1) Do you think that the 5.0L engine is constantly "knocking or pinging" when using unleaded regular?
2) Why don't you believe that is possible for the PCM to adjust for different octane levels?
To get better performance. Isn't that simple?
Why didn't they teach you in school that the octane requirement of an engine can change according to various tuning parameters.
Wow....let's go around the world AGAIN here. You don't get more HP from higher octane, you get more HP from more timing (to a point).
You do realize that you're contradicting yourself now, right?
