He said this is very unheard of even in his built supercharged or turbo'd mustangs. So to me this maybe suggest that toyabaru knew about this and simply tried to hide the detonation by giving more fuel. If anyone else can chime in on this.
Not unheard of at all, many Toyota's dating back to the 1990s, regardless or whether n/a or turbo typically would show 11 - 10:1 AFRs at WOT and high rpm - its standard safeguarding.
