Ok. I forgot about this post. I got my tune 3 months ago. Much better drivability. I’m towing a 14 Explorer with 2 bikes minimum and now a kayak. The difference is incredible. No more speed limiter, I set it to the max speed limit of 125mph ( I could’ve removed it all together, but I didn’t want to be completely unsafe.
It accelerates much better, throttle response is much improved. As of right now I gained approx. .3 mpg. That was in cool weather. I’ll guess at .5 improvement max, which will put me at 6 mpg.
We are leaving on our east trip for 2 weeks on July 2nd, so I’ll have a good feel for how it is after that trip.
