like stated i just put this in a couple of days ago and was wondering if it is normal to feel a major improvement in averall engine performance?

 

Not really 'cause the LT4 KM doesn't do much if ya got false knock.

I haven't had it do much at all,with any KR. To me it is a waste of money.

 

If you had a lot of false knock (roller rockers, exhaust, ect.) being picked up from your prior KM, and now you're not picking up that false knock and you have that timing back, then you might feel an improvement.

 

As already mentioned, you wont be able to notice any difference, but it still is a worthwhile addition.

 

The LT4 KM will only handle what it was tuned for on a Vet. Any other noises it won't do a thing,ie. internal header noise or rattles.

 

The LT4 knock module was tuned to not detect false knock caused by RR's as the LT4's came from the factory with RR's. False knock will pulling timing which affects performance. The LT4 knock module will not solve all sources of false knock.
