When using meth injection, pump gas will resist detonation much better because the methanol essentially raises the octane rating of the fuel and will allow you to run much more aggressive street tuning. This AEM kit has more features and components than any other comparably priced injection kits on the market. 1 Gallon tank with built in low level switch Boost referenced progressive controller “Boost Safe” readiness safety system Check valve integrated into nozzle to prevent unintended fluid flow One injector and two nozzles to cover a wide range of HP levels High Pressure 200psi Recirculation-style pump Progressive Controller: Start Injection Boost 1-11psi.
