| I checked with Specialty Z and would have to send my ECU out to be resocketed. My Z is my daily driver and I'm trying to minimize my downtime. I really want to do the upgrade and I'm not trying to start anything here, but what is the honest opinion on doing it from Z1? I've thought about COZ and the Ashspec as well but I've heard it's a little bit more agressive in the set up and I'm really trying to stay conservative here.
