Would you buy an engine without a rev limiter, without knowing its rev limit, and without knowing its output ?
Of course not.
Then why do you accept this from a turbo manufacturer ?
A turbocompressor purpose, as its name implies, is to provide air flow at some pressure, and it has limits.
A flow map tells you everything you need to know about the turbo. Its limits, its efficiency and what it can achieve. It also tells you the manufacturer knows about its products and has means to test and validate them.
A turbo manufacturer not showing its flow map would be like a car dealer that refuses to say more than "it is a car, and it has an engine, but i wont tell you how much HP it makes nor how high you can rev it. Use it till it blows, and sit on your warranty".
I know too well how the performance world works. When it is too good to be true, it usually is.
