Yep, Cobb stage 2 off the shelf reflash. And regardless of the method that was used to determine the MPG, I'm still pretty happy to see fuel economy like that. I'll be taking the same drive either tomorrow or Saturday so ill be sure to calculate the gallon-mileage & divide method. It's also pretty surprising because I had cruise control set around 75-80 which is prime boost range in terms of RPM. Still happy tho!
