how much is too much

I don't see why you can't DD a boosted Z. Remember, you don't see boost until you're actually on the gas pedal. Cruising around with light throttle is no different than driving around N/A. If the kit is well installed and all the lines are properly fitted and torqued you're good to go.

I'd use a 7 psi WG spring pressure for daily driving, and a boost controller to run up to 10 psi when you feel like it. I'm assuming a stage 1 kit.
