My 2016 Edge Sport was noticeably different with my Livernois tune. I was not impressed with the stock engine, power wise. IMO that power level with the tune should have been what the factory provided, being a "Sport" model. The ST was better, but had I bought one it would have to have had a tune as well. Gotta overcome all that weight.Not sure but the Edge felt very powerful in stock form also. Yank 400+ lbs off it and im sure that Fusion even in stock form is a beast.
Call Livernois or Unleashed and grab a tune. You wont be sorry.
The Fusion with the 2.7 should scoot. I've never driven one. It would REALLY scoot with a Livernois tune.
