Saturday retune to get this lml buttoned up! After some of the upgrades were done there were some functions needing turned off in the tuning as well as a map sensor adjustment for the bigger turbo. We also found some voltage issues with the map sensor and installed a new map sensor and pigtail. After some testing it should be good to go!
