LT1-LT4 Modifications - KM..whats it take for it to sense knock?

Will an LT ORY True dual dumped car have a problem with the KM pulling timing? Or does it take more than that?...RRs etc?..

shit my car doesnt sense knock i dont think it did with headers open either

I have LT's and true duals and it definitely benefited from the LT4 KM. Some do some don't.

when I dumped my exhuast after the cat, it felt less powerful over when it had the stock exhuast. So I think the LT4 KM is a good thing to have, just incase.
