wow, it just shows you how much i visit this forum... this is the first i've seen the thread!
just a minor point... on the vf23 section it states that it spools "significantly faster" than its big brother, the vf22. i would rephrase that to read "slightly faster."
basically from what i've seen on other vf22 datalogs, they're spooling only the tiniest bit slower than mine. like 50-100rpms.
as a bit of additional info, it was fitted standard on the 22b, but the vf22 could be added as a no-cost factory option.
