    Question 2 bar and pulsewidth

    My questions is im running 2 bar. Right now after 90 kpa (180 real) i killed all my timing to 0 in case of overboost after 10 psi. for any reason. Could i put my puslewidth mults to 0 also and it would kill fuel?

    Anyone think this is a good idea? Any down fall?

    not lean no fuel like a fuel shutoff rpm. but with boost. i say this caus ei have 310cc injectors and my injector duty cycle would be over the max with that boost so it could run lean anyway jsut trying to save my block in every way possible. if its a bad idea cause it will give me half the fuel instead of none then i understand.
