Well for 1 I'm not in California I'm in north Carolina and 2 the ecm isn't tunable in my car if have to get a ecm/tcm from junk yard and three the only dyno within a 2 hour drive charges way to sang much compare to others. They charge 150 just to weld mufflers and tips on. That's if u supply the new mufflers and tips and already have the old cut out. Plus from what I've read overkill does great ls4 tunes and I'm not planning heavy mods anytime soon. And I haven't had a hard time getting into touch. He replays with two days of when I send an email and that includes weekends. But thanks for answering the wideband question. I didn't know what their use was for
