Best Bang For Bang
Extremely satisfied! Was going to wait 6 months to review but after a few weeks of daily driving and putting this thing thru the test I finally decided that this is the best tune you can get for this car . Car works flawlessly and performed great with bolt on mods . Already ate 3 buddies and 2 strangers . One of them being a Ford Sho 2016 with the twin turbo 20 roll 30 roll and 40 roll
