I don't want to hijack this thread.

I realize that this is the section for ZL1s which obviously have an LT4. But what is the HP increase with a LT1 engine?

Thanks in advance.

Not much maybe 10 RWHP unless of course you tune for it.

Im curious how deleting a unmonitored down stream cat would cause a false knock ?

I wonder about this myself. If someone could give us some clarification on this would be nice.
