That actually makes sense. The other day I was coasting coming down a bridge and I was monitoring the rail pressure and I noticed that the rail pressure was absolutely not changing at all it was not increasing or decreasing it was exactly the same amount the whole time of coasting. But in that case I don’t understand why does it work while regular driving or spirited driving but not working just after coasting. Again, the high rail pressure doesn’t happen while coasting it happens when I hit low enough rpms where the dde commands the injectors to inject fuel. The regulator valve seems to be doing its job perfectly fine while driving.
