Possible to tweak JB4 for burbles/pops?
 
Hi all,

I have a 2019 C63s with JB4. The power gains are great, however I wish it'd be possible to increase the burbles and pops since the '19's aren't as aggressive as the pre-facelift models.

Is there any way to do this with JB4?

Thanks in advance!

Last time I knew u had to have a full tune to mess with that

That would require changes to injection timing which can't be done JB4 only, you'd need a warranty/lease voiding flash map for that.
