I have a roush supercharger and It used to be instant boost when I would take off in the morning but now I have no boost unitil it warms up for a few minutes. I pulled the charger and install a new bypass valve actuator and the same thing is still happening. I had a issue with my battery going dead over and over again and after I finally got that figured out multiple shop visit so no one could figure it out. It was my pigtail at my trailer lights were shorting out. Now I'm having this issue and I don't know if it's messed up the computer or what but it doesn't seem like it could have anything to do with the supercharger boost? Has anyone ever had this problem with not having any boost until the vehicle is warmed up in the morning . After it is warmed up it runs perfectly normal until it sits for about five hours and then the cycle of not having any booze starts again.
