I typed up a bunch of info, then realized I could have stated it much clearer by just saying this:

You are about to put together a combo that will rack your brain trying to get it to run right... so sell the twin turbo kit, and the Donovan, and contact Tom Nelson about doing a proper twin turbo with EFI. Yes, there are many other builders out there, but he's building some really nice stuff right now.

Another note: I used to run alot of tunnel-hulls & would suggest that you have the boat thoroughly checked out, particularly the bottom. If you start throwing power at hull that has sat for a while (and therefore a bad 'hook'), you're setting yourself up for a very bad accident.
