I have an 03 Mustang GT. It has a 75mm T/B & Plenum, Ford Racing Cold Air Intake, Ford Racing Ceramic Headers, and Flowmasters on my floor in boxes. Do I really need a tune when installed? I was thinking about a SCT if I need one. What if I dont tune?
What kind of gains either way?
Thank you Very Much!!
