On very light throttle application on decel it runs down this column and sounds much more prominent than stock, but not like the PPK tune I've heard.
Do you need to press the throttle lightly to make it do it on the PPK tune? If not they must not be shutting off the injectors on decel. Usually there are injector shutoff timers you can increase to achieve this (eg after lift off delay injector closing for 5000msec will give you crackles/pops for that time), but with so few tables available in the roms we have very little control (no injector control, no launch maps or 2-step launch boost control, no VE tables, no ECU controlled flex fuel, the list goes on). Many other cars have fully unlocked ECU tables and even custom roms with tables the stock ECU never even had allowing things like this and more but BMW aftermarket tuning support and table definitions is sadly years behind at the moment.
