with the inlet and outlet looped. Then the lines that went to the valve(turbo and wastegate) then go to the EBC step motor.

would that rectify the issue of the jump between 5 to 15 boost? Or could it be the programming?

I believe that the new Greddy Profec-spec BII allows you to set the BC to reduce turbo lag by spooling the turbos quicker or more efficiently, and also compensate for overboosting (which I cannot imagine why that should be an issue.. if you set the damn thing to 16psi, the purpose of the BC is to consistently hit 16psi, not overshoot). I believe that there are also settings to control how long the turbo will spool at the set level.

Basically, for argument sake, if the N75 valve is set up properly, would improper program settings cause the BC to pull a Cybil? Or does a problem like this solely originate from the physical set up of the valve?

Thanks for your help

did you plug the hole in the intake plumbing where the N75 connects to?

I had mine still plugged into the intake without any problems. With the new setup I just have the N75 valve plugged in, the 2 looped together and just mounted inside the fender just behind the head light.

I might plug mine back in just to get rid of that DTC. You get the car to AZ?
