I have just fitted a S144 hybrid to my car and it seems to hold back for a short time, then i get all the power at once, instead of a smooth overboost then holding boost. Its more like few seconds of lag then boost. In stage 5, the overboost is 22psi and holding 15psi. I am running standard actuator,but i still have to fit the spring. Any ideas why i am getting this lag?
