Carbon airbox, air leak, MAF malfunction

So I got carbon airbox installed, I got couple questions

1) how do I know if I get any air leak ? Since the airbox not 100% fit like oem (around MAF)

2) I feel great response and car breath smoother, how do I know if it get hitcuo like other member experience after install the airboxes ? Some timr I feel the car jerk alot bc I push on the paddle too hard and and real quick, is this kind of hickcup ?

3) how do I know if I get any air leak or MAFal function? Will I get any CEL?

By the way, pass 48h alreadt, no cel.

The Jerking you feel happens on completely stock cars too...Is it when you go up hills and floor it...it'll jerk around 3-4k RPM? Mine does this too and I only have a tune...it did it before without a tune too...As for an airleak well...they are super obvious..you can easily hear an airleak...and if no CEL after 48 hours then I doubt you'll get CEL at all

It depends on where the leak is. If it's in front of the MAF then probably not. If it's after the MAF and you have unmetered air going in then you probably will get a CEL.
