So I cleaned my MAF sensor, changed the plugs and put in silicone vacuum lines, I also put in a stage 3 brew city boost tune and 3.5 bar fule pressure regulator, and it still does the same thing (starts losing boost after I hit full boost) sometimes it is a complete animal and holds boost great and juSt about buries the turbo gauge needle in the red but other times it will hesitate going to full boost then it just will hardly have boost and feel a ton less powerful. It will also somewhat jerk/pop when I'm really giving it the rpms it feels like it's cutting out the fuel, I just want my car to have consistent power please HELP
