hey marty.. i just saw this on and immediately thought of you. its a cheap upgrade worth thinking about for your ride...
http://www.turbomalibu.com/ click the "dual fuel system". its alittle redneck engineering but its sooo simple and automatically switches from 89 or 93 octane to 116 octan under boost

since the injectors are pull to ground both sets are wired to the ecm, and the power is switched from one set of incjetors to another.. allowing higher boost... (remember to turn on the 116 octane fuelpump at a lower boost setting;-) ) just somthing to considder
you could even run methanol on the second set, just by running proportionately larger injectors and adjusting fuelpressure so both fuelsystems deliver furl coresponding o the oxygen in the chamber... the same map should work for both...
sorry for the sidetrack... now for some paint pictures please
