Follow up- Turbo goes out at 37,000 miles

Question

One more peculiar thing……before my turbo went out I was getting about 7.8 mpg.  After several trips (350 miles) after the new turbo and actuator were installed…..I’m getting 11.4.  I know that is a very short number of miles to get a real number for mpg….but I never got that kind of mileage…comments??  And yes, I know there isn’t any way that RV towing a Tahoe should get that kind of mileage….

Does it indicate the original turbo was defective since purchase? Cost you a bunch of gasoline.

Perhaps the tuning was deliberately derated before?
