Ah, so they are, sorry. I was mostly perusing jetting sizes and saw lots of 110+ mains, which is what you'd use on pre-gens. New-gens work best by downsizing mains to 96. Jetting DB on FactoryPro website shows most people using 90-94 mains on Stg2 kit.
Maverick9611 has similar mid-range stumbles and tried all sorts of main-jet adjustments to no avail. Turned out he had aftermarket FP pre-gen needles in his new-gen,. Going back to all-stock conguration fixed his mid-range stumble completely.
