The tune HP logic had stock timing map but seems he compensated with a rich tune. HP Logic tune would decrease the motor's life over time.
This tune is a solid 11.7-11.8 AFR but with less timing and still conservative compared to some other builds on this forum.
The tune difference is night and day.
