Honestly, boost is somewhat irrelevant....its a hard adaptation to make but if you get hung up on looking at boost you will thing there is soemthing wrong
The ecoboost cars are targeting torque levels..it will do whatever is necessary to achieve that torque so boost will be all over the place
I tune for boost because its what i like and what im comfortable with and thats how most people prefer it too...
I can tune either way for people but in the low end and midrange you dont need as much boost for s given torque level so boost goes down and people think something is wrong
