The problem with leaning the fuel right out is that you run the risk of melting the internals of your engine, particularly your pistons. It's happened to a friend's car... the water injection didn't kick in, but the computer had failed to compensate for this, so it ran lean while boosting aaaaaaand boom goes a piston. It's not something I'd like to use as an insurance failsafe.
Just be very wary of what you're doing.

Yeah tuning is key.
Just like he said. 100 whp on just meth injection alone is pushing it. That doesnt mean that is hasn't been done because it can happen. There are a bunch of things that you need to think about though:
1, The turbo should be capable of more boost. (some factory turbos cant make much more boost than what they were originally intended to produce)
2, Injector size when you start increasing boost you need to compensate with increasing the fuel injector capacity
3, TUNING. Probably the most important out of everything I've said. But if your car does not have the capability of doing the first two... you're pretty much out of luck.
Make sure you bring it to someone who knows how to tune. These people are very few and far between. Tuning is an art in itself there's more to it than maintaining a/f ratios and leaning out the a/f.
I still stand by what I said. Meth/water injection DOES NOT replace built internals. Meth/water injection is a great addition if your car would benefit from it but you need to carefully analyze if your will in fact benefit from this. But just like any other mod. When you start making additions in order to make your car run properly you're adding on the extra risk of having something fail.
