So after Fuse Pull 24hrs ago on my 2014 SS, filled it up with 93Oct, had a quarter tank of 91Oct left in it. I can agree to what the most say, much better in first gear, better idle, and much more smooth during acceleration. I think it sounded a little more dirty before but still get my plops and rattles
The Engine is not so shaky anymore, I still think you can feel when its running in the wrong fuel map, now its like it should be with an new car not so rough.
Gears going better in too, don't know why that is but it should has a reason.
Works the Same like on 2013 or lower years.
Next will be the Fuse Pull for the Exhaust just to try
Just do it and drive it, like the most say, feels like a newer car.
