High Boost + W.I

[schwitzer turbo]

hey hey all i wont bore you with chit chat. Straight to the Point.

What would be the optimal way to use Water injection on my setup.

Currently the car has a Compression ratio of 7.5.1 its a 1500 cc with a Tdo4H turbo. 400cc injectors+ Megasquirt Pro.
Currently the car is Boosting 1.5 bar on Pump gas(95octane). So i bought this W.I Kit. what will be the best way to use it.

PS:No one has Ever Research or devloped my engine.

anyway if you where tuning the car how would you tune it. (My Megasquirt can do progressive Nitrious/methonal.)

Start injection meth a 1.3bar (my low boost point) all the way upto 1.8 bar
or Start injection @.5 bar and advance timing Heavy all the way to 1.8 bars.

I ask these question because i dont know and dont wanna Appear to be a Complete Nuub. Please assist where you can. i Finally got the kit and want to start making POWER!
