I have the Livernois 93 tune on my 21 3.5 EB. My truck bone stock ran a 13.99 at 99 according to my Draggy. My truck now with much heavier wheels and tire runs a 13.30 at 104 with a full tank of fuel.
I have a 2021 Lariat F-150 with a 3.5 EB that had the rough idle issue. I recently purchased and installed the Livernois 93 performance tune in my Truck and the rough idle issue is gone. Just wanted to let you all know.
I contacted Whipple today and they said they can tune a 2021 3.5 Eco and they are coming out with a stage 1 tuning package very very soon. They already tuned a 2021 F-150Coyote with a 3.0 Whipple.
