Hey guys so i've recently noticed my engine light coming on under high boost its not always on only when it gets to peak boost of whatever setting its on. I have 4 different boost settings lowest being 14psi highest 20psi. I've got to say this worries me I don't really have any idea why it's doing this. Thought it might be the engine knocking. Could it be something in the tune not right? what do I do about it. Car is 330hp with factory internals. Also it flickers on and off it's not a constant light on.
