"The car is a hybrid - mid-year S chassis, 3.2 brakes (currently), 915 trans, 21 & 30 t/bars."

You have a show stopper in the mix.
Your 915 tranny will not endure much more than 350ft/lb of torque over the long haul. Unless you plan a tranny upgrade you should forget about twin plugs and 1.0bar of boost. Given the light weight and gearing advantage you will have an incredibly fast car without all that.
