SoCal people that are tuned

I want to ask all the So Cal folks that are tuned how their cars are running with a tune, because it's well known we get pretty bad quality fuel out here. Just wondering before I pull the trigger on a stratified tune.

For anyone wondering, I would put Costco gas in a "below top-tier" quality (former employee, and it used to be Sinclair fuel with a "modified detergents package" if I remember correctly). Stay away from Arco and similar brands. Been tuned for quite a long time and even at $.10/gal delta, it's about a dollar extra to put good gas in and that makes it easy to justify IMHO.
