It doesn't create a sustained lean condition because the fuel isn't gradually depleted...instead, there is no fuel at all delivered to ignite.

I'm with everyone else on this....keep it installed just as insurance. Unless you're running at the ragged edge of boost intentionally, the thing will never come into play and you'll not even know it's there.
Mark H. 1987 930, GP White, Wevo shifter, Borla exhaust, stock everything else. The result of a massive Pelicanite good will fire recovery effort. Truely an open book, ready for the slippery slopes to modification.
