There's also Boosted Tuning in Chico. Jay does great work tuning. He can also tune your car on a dyno if you prefer. Thunderhill, here in willows has an awd dyno which he has access to.
I head up to redding to the street legal drags a couple times a season and im usually the only subie there. It'd be cool to get more subie guys out there racing. Ill defenitely be out there once it opens up again.
