what size motor?  
doesnt the fact that he has a 4.0L have to enter into the equation somewhere?  
this conversation is a little over my head, but it seems like the larger engine would allow his wastegate to maintain the lower boost levels as it (the motor) would consume more of the charge air… correct??
