Got a 2016 3.5 with 92,000 miles. Its got individual intakes feeding each turbo, throttle body spacer, and a 75 hp tune that requires 93 octane. Cuts off in 4th gear at 130. Wont hook til halfway through 2nd with traction control on. Put a water pump on at 90,000 and will do another one at 180,000. Got buddies running durajunks, cummins, and strokes…..they roll slow around the ecoboost, I’ve done spanked all of em any way they want to try. I also have a F-250 powerstroke and a 5.4 triton. 5.4 is got 350,000 on it with a buncha motor mods. I am religious on maintenance but I drive em like they stole. Ecoboost works like a diesel the more air you give it the higher the fuel mph gets.
