2020 M340iX won't pop & bang when reving *TUNED*

MHD Stage 1 tuned my M340i and set the bangs & pops/burbles to be aggressive and the way I like them. They're completely fine when driving but if I'm in neutral or parked and rev the car, they seem to be nonexistent. My exhaust valves are forced open. I try low RPMs and high RPMS. I don't see any option with MHD that could affect that. There were OEM burbles before I tuned so I'm not sure what changed other than tuning it to be more aggressive. Also, all parts are stock.

*If it's something stupid please have mercy on me.. I'm learning as I go everyday about cars in general*

If anyone is going through this, check your minimum speed. I was blind and had it set to 15MPH. Set it to 0.
