They don’t recommend using a straight performance tune while towing. Gearing and shift strategies too aggressive. You would need to purchase a performance tow tune and they can make it shift however you want. Plenty of 5 star f150s out there towing the shit outta stuff. And 5 star, unlike livernois, actually calibrates there tunes with trucks and fully loaded trailers to make the beat ECU map for each application. That’s why 5 star is the preferred vendor over Livernois (which by the way is wayyyyu too expensive, and 5 star tunes make more power)
The key though is to not just take the first tune they send you and say “oh it’s good”. I’ve had 13 revisions done to mine and I guarantee you I make over 400rwhp and rwtq with how great they have it dialed in. 23psi of boost, -0.96 OAR and 0.44 degrees ok knock at WOT. 2016 el platinum 3” lift on 35s and 3.73s runs a 0-60 in 5.7 secs
Revisions are key!
LMS is GREAT on my edge, but Like you said, the delivery platform leaves A LOT to be desired. None of the 3 logged and custom tuners I have tried after LMS, still can’t compete. So they have their place also.
With that said, they I am sure would do fine on the Expy, they are not a recommended one from me simply because they don’t use a platform that can be used in other places.
