Car: 2019 Jeep Wrangler rubicon

Hello new to forum, installed jb4 on 2019 Jeep Wrangler rubicon 2.0 turbo, no issues. Apparently map 1 is the default map, I have not really “tested “ the install yet, but with just rapid exceleration there seems to be a harder pull. My experience is with liter bikes, and fuel management system enhancements are noticeable immediately without much “tuning”. I’m interested in low to midrange improvement In performance. Does this mean I need to change existing map or is there something available that would become my go to map. Any help much appreciated. Thanks
