That fact that you stated you have to let the car warm up in order to get full boost is sad. That's what you should be doing before going full boost anyway! Unless you like adding wear and tear to the car for no reason! Wow...
I mean the car is warmed up but i have to drive it around for like 10-15 min before it will. I let the car warm up 5-10 minutes in my garage.
