Look at the map. Better yet, it would be awesome if an OM617's rpm can be plotted across these maps, would make understanding them way easier.
The 60 trim optimizes for higher rpms. GSXR seemed think his 55 trim was a better balance, that's the stock 3.5L turbo.
Spooling is trickier. The maps don't really help with that. Probably gonna have to rely on actual experience. Anyways, I doubt another old wastegated turbo would be any better than the stock one. It's either going for smaller turbine housing (choking off higher rpm) or VNT.
