IMO .024 on your top ring and .026 on your second.

so should your second ring always be a bigger gap? i thought i was suppose to be tighter?

New tech. in rings recommend that the second ring gap be slightly larger so that it there is any pressure build up between the rings it will escape past the second ring and not lift the top ring land.
I would not run a Plasma molly ring for a FI or nitrous engine you need to have a ductal Iron or steel ring for this.
I have run this .024/.026 gap with as much as 30 Psi of boost with no problems and it would be fine for twin turbos.
