280 tank max, hitting low light, on ZZP PCM, 3.4, and supporting mods.
Added more mods and started tuning: WELL running way faster and getting 340-360 a tank usually city and highway. Max was 380 once on my mods!
See sig for mods!
It's all in the TUNING and a decent tune up, or taking care of your items that contribute to mpg.
