The increase in pressure multiples should be more than 1 times higher and the result was 10 + times with less efficiency.

What caused this result.Anyone knows?

Is it due to 494? The ratio is correct,but the magnification is high.
Or it is because the main circuit? Will the parameters of the main circuit have such a big impact?

Here is the datasheet

I really hope you guys can help me!Thank you so much.
