CA is a great state to own a car, no salt added. My Z is running good. I'm just running a conservative 14Psi on the Sport500s. I've been trying to save up for the 555cc injectors and ecu program, but $ is always a problem.
I might try the toulene thing too after I get the upgrades. 20Psi on 95+ octane sounds very tempting.
The humidity and 100 degree weather here chokes the Z to death however.
