Hello, I bought my 2016 GT with an Air Raid intake, Roush X pipe and axle back. The car sounded amazing, like a WWII fighter plane. Eventually I figured I would trade out the CAI and get a tune so I purchased the Ford Performance Pack 2 (CAI, throttle body and tuner) but after installation the car sounds terrible. Very muffled and MUCH quieter than it was previously. Another weird thing I noticed was it seems to be idling lower, around 600 rpm. Hhas anyone had a similar problem or know a fix?
