what people don't always realise about P90s is they all have quite high output, if they have the traditional design. The reason for this is they have two bar magnets, rather than the one that vintage humbuckers have. They also have quite a surprising amount of low-end.
For bite I would suggest Nantuckets, but if output is critical for you then the Supermassive.. but the Nantuckets aren't exactly short of output.
The Black Dove is a MIM Fender as far as I know. I like Mexico Fenders, they make them properly. I think the guitars just have two weak points - the poly finish, and also the pickups. Usually, they have good hardware, wood and other electronic parts. I think you will notice a worthwhile improvement with new pickups.
Cool guitar by the way 8)
(edit: you can sometimes argue to change the trem block on a MIM fender, but of course the Black Dove doesn't have one. Check the bridge saddles are real steel with a magnet - I think they should be, but if not you will get some more bite with a cheap upgrade of those)
