How much power should i be making once meth injected??

[The Godfather]

yeah i gathered that i wont see power gains without tuning, i plan on getting it tuned right once installed,

im just after a rough idea on how much there is to gain, power wise...

100% water..... run 10-15% of water to fuel - with more timing and 24psi @9000rpm?? 10% increase in power? 15hp?

M50:W50 ....... 15-20% to fuelwith more timing and 24psi @9000rpm?? 20% increase? 30hp???

M100% ....... 20-25% to fuelwith more timing and 24psi @9000rpm?? 20-80% is that possible?
