If I was worried about power I'd just get a protune before an OTS flash probably. I'm plenty happy with the power a piggyback yields. I'm moreso just looking for smoothness and reliability for now.

Also new update. Car was put back in bypass mode after getting the lights again with stage 1. Only this time the lights and hesitations happened while in bypass mode. First time in over 1200 miles of driving its done that. So it maybe be more than just a bad module/harness.

Trying to get it over to the dealer this week. Hoping it's something silly. I'm exhausted and just want to enjoy my new car for more than a day at a time lol
