So what's the mileage/performance like after the Stage 2 fix?
After putting more miles on the car after the Phase 2 fix, I am noticing better mileage than before. I previously stated that that I didn't notice any change in my mileage after the fix but now I am seeing a few more mpg. Nothing drastic but enough to notice.
NOW, I don't know if this is due to the Phase 2 fix or other contributing factors.
1. I did the fix right around when the weather was getting nicer so the "summer blend" might have a factor. But even compared to my summer mileage from last year I get better mileage now.
2. I have only had the car for 14 months so last summer was my only experience with "summer mileage" and the car had low miles at the time. I keep hearing that the mileage gets better after 10k. This year I'm past that 10k mark and it could be just the engine being broken in and reaching its full potential.
3. Could be a combination of all 3.
Either way, I am noticing my mileage going up with the same daily commute; 80 mile commute, 90% highway, cruise control set at 65-67 mph. The car calculates averaging 59-62 mpg, yes I know this is not accurate, whereas last summer I was averaging 52-57 mpg.
