@frito2004 The mod calculates the smoke based on the condition of several engine components. In the settings, you are able to change the gloabal (or per vehicle) smoke intensity. You can also change the vehicle profile and choose classic over modern engine. This should increase the smoke. Hope this helps.
@Jannik7755365 Thank you for your feedback. I packaged the mod wrong, so it did not work. I am fixing it now and reuploading it!
