Greetings, trying to tune my friend's 2016 3.7 mustang. He wants to have the car make more power along with a pop and bang tune on deceleration. Was wondering if anyone out there has done this and has any tune file I can look at or lend me on what I need to do before I mess with the car. Thanks, in advanced

Current mods on the car:

BBK long tube headers
BBK high flow catted mid-pipe
JLT CAI
