I have noticed a air leak between the turbos.
I usually drive around 70 on the interstates,but lately I have dropped down to 60-65 and mpg improved to about 5.45 from 5.1
I am going to try the progressive shifting and see if i can get the air leak fixed.I used to run my cruise control at 70 mph down I-95 a lot.
