try flipping it 180 degrees, part going into tip looks backwards from the N75 on my car, but I use a stocker
N75 ECS J valve installed and got a check engine P1289 with 9PSI boost
I tried to use it with my turboxs MBC and got this code. than I did just the Jvalve and still have this code.

- Check and make sure you don't have a short in your N75 plug or wiring (do the same for the N249 plug as they share that fuse).
- Pull the fuse again to see if it's fried again. If it is, that will confirm a short - if not and the code is gone, reset the ECU by pulling a battery terminal and you should be good.
