I've seen charts on performance gains for just adding the Cobb AP alone. I have not seen data on how much more power and torque can be gained from adding intake and or exhaust in addition. Anyone done this stepwise?

I guess same for JB4? Anyone added the JB4 first and then further tuned? Is it diminishing returns or not?
