I'm considering starting to mod my car. Im looking into the Cobb stages primarily, because they seem to have a pretty good reputation. My '15 FiST is, and will continue to be my DD though, so I don't want to start going parts crazy before I make sure that I won't turn my car into a money pit. My biggest fear is that I will get to Cobb stage 2, and 15,000 miles later something will break and end up costing me a bunch of money/ down time. How reliable have your cars been since tuning/modding? Does any one daily their modded FiST without any drama whatsoever? How many miles do you have on your modded cars?
