2010 5.4. Flow master CAI, JBA headers, flowmaster super 44muffler. I have very little power below 2k rpms. I have an SCT 7015 tuner. Would a custom tune be needed with what I have? Is this the right tuner for my truck? I tried calling SCT but they wouldn’t help because they said technically it’s for an F150 5.4, but should work for the raptor.
