Final drive ratios can be changed but options are limited and you have to tear apart the trans to do so, or swap a whole trans. I plan on getting taller tires one day too to try and bring the RPM down a little. Been looking into a kill switch, the injectors and coils share a common power wire and the computer controls all their grounds for activation so interrupting that power wire would be a kill switch option. JediSol uses a switch in line with his crank position sensor and one day I am going to test interrupting one wire and see if that will work for a kill switch, I know unplugging the sensor works to kill it but I'm not sure yet if 1 wire will cause the engine to stop.
