My 2007 GT 5-speed gets about 16-17 city and 24.75 highway when I drive right (cruise set around 78), 14/21 when I don't.

My 2006 GT automatic got 14-15 city and 21 highway when driven right, 12.5/18 when I didn't.

2006 GT was computer and hand verified; the 2007 is all hand. I went with a deluxe GT to avoid the door panel mess falling again, but the computer and hand were both very close.

I may be wrong, but I believe the 2011-2014 5.0s are extremely close, if not a slight bit higher than the 4.6 3vs.

Current:
2007 Mustang GT 302 stroker 6060 swap, 3.73 gears, Hidden Hitch Receiver, Barton Short Throw, JBA LTs, Borla Touring Axle Back, Lito tuned SCT X4. BMR SP009, Bilsteins, J&M CC plates, J&M LCAs. 4 Piston Brembos
DOB GT450 with VMP Gen II 2.3 TVS | 13/14 GT500 HE & IWP | GT500 hat & DW340s | FRPP 52lb | CMS Stage 2 Blower Cams | Comp 113 Springs & Retainers | 8 rib conversion | Track Spec GT500 Vents | PTFE Heat Barriers
