    Yes I have one. Cut the top off and changed the spring (I think to 14psi) cannot remember. Need to find it.

    Had a thought last night - moment of clarity - when you were talking about using an MBC, you meant to have it paralleled with the N75 to create an additional control signal. I was thinking you were trying to use it to modify the boost pressure I'm using to hold the wastegate shut - hence why I couldn't see how it would work.
    Yes both together.

    Spray some EGR cleaner into the side port to decoke the chamber. I think its just coked up a little and needs to be run. If the pressure from the manifold is equal to the pressure applied to the top port then the pre-load is the spring (10-11psi). The N75 control boost is operating the valve over the preload value. What's needed is a logrun to 1) to check the N75 duty cycle and the pressures at which it has applied control to 2) to check the range of the N75 duty cycle 3) identify areas of the boost that are over target / under target 4) identify improvement in the boost pattern to limit faults and limp mode 5) possibly remap the N75 map to broaden the duty cycle tolerance.

    Good news about the wheels - your audience awaits. Love your build and the humorous detailed journey you've shared. An RR day will be a good datum point for advancing your project.

                        • Cartridge received back today. Gave me a chuckle when I proceeded to open it and open it and open it - three levels of improvised cardboard origami. Top marks.

                          • No problem!

                            I did a bit of unwrapping of my own today too...







                            Shame I didn't have time to wash it.

                            Bigger shame that they wont fit over my big bakes (when I fit them)
