Dome ratio for 872 R on 91 premium

[Maximum1]

I was thinking 13:1 for Trygstads 872 on 91 premium or 13.5:1 with 2-3 gal of AV GAS @ 2300'. Does it sound safe?

Is there that much of a difference between 13.2 and 14.4 ??

I would go with dave's recommendation We drag race and can get fuel easy(more psi)is not always the answer.The different for use was throttle response and @7000 feet it was noticeable.Cheers
