installed the much less worn turbo today. filled up with gas, topped off oil and now we'll see what happens. shouldn't take too long for results since i put about 110 miles on it a day.

It was an ECU reflash recall to fix stumbling issues.

Data point - I just drive ALB- PVD- Cape Cod - PVD ALB this week between 70-80mph and report 26.2 mpg in my trip odometer Im in the boost regime at that speed so my T5 would be thirstier than your GLT
