Spark Plug Question

After tons of testing with my flex tune, this is what I've come to find being the ideal NGK gaps with stock fueling and stock turbos with max effort of 26PSI:

NGK 97506

.022+ for Stage 1, 2, or 2+ with ACN 91
.022 for Stage 2 or 2+ with E30
.020 for Stage 2 or 2+ with E50 > E60
.018 for Stage 2 or 2+ with E85

NGK Flex Fuel Plugs (SILZKBR8F8S)

.022 for Stage 2, 2+ for anything 91 > E50
.020 for Stage 2, 2+ for anything 91 > E85 (Flex)
.018 for Stage 2, 2+ for full E85 all the time tunes
