Swirl flaps

[Glen07]

Hi guys,

I just have a query about swirl flaps. So I’ve not yet had them removed but I’m having a stage 1 remap being done soon with I’m already including EGR, DPF deletes (work already done to remove). I’m wondering if also adding a swirl flap delete to the map would still be beneficial even with them physically still in place? Also, if I add the delete onto the map, would that just keep the ports open/closed at the time or would it just stop the ECU from reading?
