the 33’s are heavier and harder to spin. My mpgs were better after the tune also.I have had 5-Star tune installed for 10k miles now. I tow a 2500# camper in the mtns of CO pretty aggressively. It's great. I use the 87 daily/tow tune. I am happy with 5 Star overall. Sadly my MPG is hovering around 20 with 33in Duratracs. That's a decrease from 14 that I WAS averaging before. My old Focus ST shot UP in MPG with a COBB tune, so I was a tad disappointing with this one decreasing.
Regards
Edit
Mine is on stock tires.
21.9 mpg before tune in drive mode
24.6 mpg after tune in drive mode
I use Sport mode only now...21 mpg
