Kurt, that is the one thing I've never really liked about the new EFI's like the 525/600/700sci... You crank it over, it fires and immediately goes to 1500-2000 rpms and slowly settles down... When I fire up I try to keep it at or around idle (as much as my carbs allow without stalling) and once I see oil pressure I'll raise it up to 1200 until it's warm and driveable.
I just did a tear-down for one of my engines for a 250 hr refresh and everything internally was perrrrfect.
