Bama; Thanks guess i can try it and always return to stock if i need better mileage on certain trips.
Or just try to drive it with the eco notification on as much as possible. I’m trying to see how much gas it uses over a longer time though. I have 93 octane in it and I also still added a little bit of the octane booster to the gas cans. But really I haven’t found a downside to the pv3 tuner.
