@Deep8174 yeah I can. I ran the preloaded tunes from the x4 I bought prior to tuning with 5 Star. 2016 el platinum. The preloaded tunes definitely woke the truck up a bit but performance is nowhere near what even a base tune from 5 Star put out. It was night and day. The truck ran smoother, there was no engine knock, boost and timing were more consistent and the best part was the transmission shifted so smoothly. I was actually surprised at how much of a change there was over the pre loaded tunes. They are good and all but nothing compared to a custom tune. I was afraid to open her up on the canned tunes after running them for a few days and just seeing and feeling how the truck handled them. Plugged the 5 Star tune in and never looked back. I’ve had 2 2016 expeditions on 93 and e30 and currently run their base 93 and e50 tunes on my 2020 f150 3.5L. It’s a monster
