Casual Fanatic
I don't even know what to say, I don't even recognize this car anymore. This paired with the CAI is pretty incredible. I also had issues with 2nd to 3rd gear, but any lag between shifts is entirely gone. The tunes they provide turned my 2.0T AWD fusion into an ecobeast! Thanks Steeda!

Worth it!
Got the tuner and custom tune after having the Steeda CAI in my 2014 Fusion Titanium for about a month and a half. It was a bit of a struggle to justify the cost but once I got the tuner and thenot just 2 days later I received the custom tune file, I was extremely satisfied. The first time I drove the car after uploading the tune, I immediately noticed no more lag on the 2nd to 3rd gear shift. This shift was terrible from the first day I had my fusion and now the shifts are more crisp and happen at the correct time, through all 5 shifts. I have an AWD fusion and burying the throttle in 2nd gear it seems to lift the car up, using all the power to shoot the car forward thru 3rd gear and into 4th much more than previously. The turbo spools up quicker and paired with the CAI there is no question this car is now capable of what Ford meant it to be - a perky 4 cylinder turbo with crisp response. I'd recommend this to anyone who wants better throttle and turbo response with smoother shifts, not just those who want increased horsepower. Gas mileage is TBD as I just started driving with the tunew a couple days ago.
