Now that my LT,s are in i forgot about the LT4 knock Modual.
Should i go get one ASAP? where do i get it from where do they go? Will i feel a dif in my car with thme installed?

 

some people feel a difference, some dont... I'd say with all that extra noise under the hood now, It cant hurt for the 40 bux it costs to your door.... Give it a shot..

 

Where do i get them from autozone? where do they go?

i've got two pcms (one with and the other without the km) and honestly, i dont feel one lick of a difference...

 

I didnt really believe in the LT4 KM making a difference until I put one in. My car felt sluggish and then I put in the LT4 KM and it runs like a whole different car. May as well throw one in since its cheap. $35 from gmpartsdirect to my door. Some people feel a difference some dont but I say go for it.

 

I felt a difference with the KM. My car used to be sluggish in first gear and have a stumble at idle. After replacing the KM it is 100% better.
