Will the access port give me any advantage with stock parts on the performance package? I can already tweak it while I am driving already. The performance pack already has the gauge modes and boost, PSI on the terminal. My car also has the higher gear ratio. Tell me what will I gain for...
I was wondering what kind of mod should I get first that would not void the warranty for my ecoboost Mustang? Does anybody know of a good intercooler to get?
Thanks!
