Hi from CA

I'd go with ALPs as they are updated frequently, and also have a hardware advantage with more sensors per head, etc. You'll pay a bit more, but worth it in the long run. I'm not familiar with Premier in Fremont. Not all installers are the same. Just make sure they place the heads where you tell them to (with help from everyone here) and make sure they are level/square on all axis. Also, chime back here after the install with photos, etc. Send me a PM if you want to get tested.

Very good advice. My installer put the heads level and square the first time, but then when I asked them to move the heads out a bit, they installed them toe out. I then had to tell them to realign them so that they were level and square. Clearly the second person who worked on my car they didn't know what he was doing. Some of their people seem to be experienced with jammer installs and some of them do not.
