I have 2014 Flex (non ecoboost) and pull a small travel trailer which I keep just under the 4500 lb tow limit. I could use a little more horse power and torque. I'm considering a tuner to help with that. I'm pretty conservative and won't be pushing it much. What's your opinions? Here we are all set to go. Yes, we named our trailer and SUV.
