I mainly worried cause I paid extra for 100k mile warranty and would hate to void that

My opinion, a plug&play is much better because you remove it and the car will go for standard settings.
Repro if you have a service and they make some update to the system...gone.
Warranty also gone if they notice any trace Of repro.
