I imagine that many of you have already studied n75. I have several questions: on certain models there is an adjustment screw while playing. I understand that this changes the 'frequency' speed of the actuator by moving the body of the solenoid. On the other hand, concerning the sealing of the metal piston against plastic, I find it crap. Yes, N75 does not leak if I blow through my mouth, but if I blow 1 bar (bicycle pump) it always leaks. There is indeed a restriction on the turbo pressure inlet. The question I ask myself is what amount of pressure passes through n75? because inevitably at a given moment the pressure on the small piston/spring opens it

Throw any old n75 that you have to the bin and use a TFSI unit. 100% new, better design, holds pressure perfectly, has a faster response and better control of the turbo, and its WAY cheaper and available everywhere. You need to change KFLDTV in your tune.

Thank me later
