Timing is up in the mid 30s at certain points in the stock timing table. You want to fire earlier at high rpm because combustion takes time. Also with a less dense charge you want to fire earlier as again combustion takes longer. I haven't looked at his log as datazap on a phone is hard work. I'm not saying Ken's maps are OK, just want to make people aware that there's context that needs considering with timing. One thing that does always look odd in Ken's maps is the flat timing target. Typically you want timing higher as RPM increases. |

I was thinking the same, Also I'm wondering why actual load is so low compared to target load under WOT? I mean actual load should be somewhat close to target under WOT right? |

Ideally they should be close in all scenarios not just WOT. The target boost is derived from the taget load. If the target boost is not met it could be for a lot of reasons but most commonly boost leak or bad turbos. In that scenario the actual load will fall short.
