I got a simple question.
I just wanted to know how the boost cut in crome works.
Does it just cut the fuel and you end up pumping just air in the cylinders at that giving psi
Or is there more to it?

Also wouldn't that be bad, wouldn't it cause the motor to be very lean.

Just trying to figure it out, ill be finishing up my kit in a few months and wanted to know if it was something i should use or just rely on the wastegate.

 

should cut fuel and spark, although im not 100% certain. also just putting air in the cylinders is ok as long as there is NO fuel going in with it. you will have a lean condition, but no fuel to make a lean combustion.
