Boost problem

[prj]

Irrelevant. There is barely any difference in the map, the biggest difference is the lower 6.5k rev limiter and some idle control maps.

But my car spins to 7500 rpm.

Thank you. Based on igor136's comment that he is getting 7500 RPM before the limiter cuts in, is the handshake between the motor ECU and the autobox ECU via pins T55/51 and T55/54 resulting in the 6500 RPM limit and without that handshake, the motor ECU reverts back to the 7200/7500 limit?

Today I tested a boost with the new N75 (disconnected), and i have 1.4 bar on the display.
This is something new. So, either the problem in leek or in ECU.
But I can not find the leek. I try every day and I'm already crazy. Boost on this car is a jackpot.

And yes, the engine runs a little rough.

I am. Leave it alone for 10 minutes with a pressure of 1.2 bar. No leaks.

I had an idea to spray with start spray around the engine. But at the petrol engine it does not help.

Maybe Gasket on intake manifold? How do I test it? Rubber rings on the injectors are new.
One-way valve is new on the intake manifold.

[igor136]

What about the one way valve from the IM to the PCV system?
