Now I have 0.57 on 5th gear with full gas. Is it ok, or should be decreased?

The device is not very sharp, so 0.07 should be added to indication

What is the measurement scale? Bars? Most here will have boost showing in psi (pounds per square inch) . If yours is in bars it equates to around 9psi.
My TD42i in stock factory form had a maximum boost of about 8.5psi. With mild tuning it now has a maximum of about 13.5 psi. Some folk go higher. You also need to know what your exhaust gas temperatures are. Easy to increase boost & just as easy to destroy turbos which get too hot!

Thank you. Do you make some regulations on your injection pump when rise pressure? What fuel consumption do you have now?

I changed engine on my GQ. Td42 to Td42T. New engine was from right-handed Safari 1994. So steering propellershaft prevents wastegate actuator from taking it's place. So I have to modify it's attach and not sure it's in original position now.

my stock turbo was 6lb boost got a denco turbo fitted boosted to 14lb with the fuel pressure adjusted with new injectors goes a lot better.iI was told not to go over 14lb as some people go up to 18lb an so on but the old 4.2 will damage pistons. so I was told by the spaner man who knows alot about the nissans
