I Have a 3.5 Ecoboost MKS that i tuned with LMS just the 91 performance still 2 bar map. I'm going on a family road trip. Would it be ok to leave the tune on there for the trip or should i return it to stock for the journey. the engine only has 4000 miles on it. thanks

It will be fine. I drive my car 99% on the time on my unleashed 93 performance tune. I actually get better fuel mileage with the tune. I just took my SHO on a 6 hour round trip ride to cape cod. Car loaded to the gills with beach stuff and golf equipment. Still got 26/27mpg going 80 the entire way.
Why wouldn't you. You use the tune around town and such.
I've taken probably 15k worth of 200+ mile road trips tuned. My car is setup for 91. I didn't want a 93 tune because that fuel isn't available locally here and I like to hit the open road a ton.
