im useless at psi maths lol so does anyone know what 10 psi is in kpa ? cars is setup for 145 kpa overboost which i think is 7 psi am i right?


why do people say they are nasty ? all depends on what you do with them, ok i know most people get boost happy and turn the screw under bonnet, without any overboost protection enabled, causeing overboost and spikes,

but if used correctly then they are ok, megasquirt has the option for overboosting which is a good thing as it cuts out spark or fuel if boost hits pre overboost level.
