It'll pop and bang in sport mode all day long in Sport - I rarely use Normal Mode (but down the country lanes I prefer Track but with the suspension set to normal as the 4wd is configured better to how I enjoy it) and have never used drift mode.
The exhaust valve in "sport" gives you the pops.
It's a gimmick at the end of the day. Sport just makes the throttle linear instead of progressive and over-fuels a bit to create the pop.
Good info...
We offer a service to turn of the pops and burbles in normal mode caused by the latest PCM update, becase some old people like us, dont like it.
We offer all manner of crackles options for all cals, including all tunes via the COBB Handset too.
As much, or as little crackling as you like, especially if the cats are removed so we can disable the CAT thermal control routines.
Its a VERY popular feature.
P.S:
Just to clarify, its actually targeted
lean to cause the crackles, but its still technically over-fuelling, since normally there is none at all. LOL
