yeah your right but i am not the only one using the car
im also thinking that the stock maps are really rich at high load, more boost = more load, less boost = less load
also the more open the throttle, the turbulence and resistance from the throttle body (pretty negligible thats the theory to the warm air intake thats popular in the states, gives slight fuel consumption improvements due to using less dense air etc, less power, more throttle, less resistance)
also, wouldnt more boost = more load?
so running lower boost on a day to day basis (if you kept the driving style the same) would also be better
