Do not waste your money. This stuff is not at a point that is worth your time or money!!
their computer system is far too spotty and simply tricks your computer into thinking it needs to run leaner. it does not work reliably. it destroyed my idle and I got no continuing mileage gain. I removed the computer (piggy back) and now its back to normal and runs great again but now I intend to install a megasquirt to control the fuel system while using the fuel heater and hydrogen from the hafc. Ill start a new thread off when this happens.
That took some guts to say after all the flaming you took regarding this. I appreciate you coming back with your final thoughts.
