To fix your lag you can get the aforementioned update OR drive in manual mode by putting the shifter in sport and selecting a gear with the paddles.
I constantly drive the car in manual mode and it's where it's noticeably present. I considered the JB4 because it has better numbers coming from stock vs the Cobb. I see Cobb has more options but this will be my first performance upgrade, and I don't plan on going too crazy on the car with aftermarket mods. At most, I was planning FBO w/ E85...
