I think they are allowed to change safety parameters and not have to worry about CARB. Don't matter as they will have to get the 2024 CARB certification going soon.Absolutely not.
Once a stock/factory tune makes the grade, it's illegal in CA to modify that tune.
There used to be CA legal tunes, but, they could ONLY alter the WOT throttle performance. Part throttle and idle were not to be touched.
Now IF Speed had BOTH tunes certified as legal in CA, then life is good!
Lots of unanswered questions here.
