How good are the mail tune guys at desensitizing the lt1 knock module?

With LTs and RRs is it still a very good idea to get the LT4KM even though your tune has desensitized the stock one?

 

If the knock has been tuned in the pcm you dont need a LT4 KM but as far as I know a LT4 KM is better then tuning the knock from the pcm because I heard some guy tune it a way that it does not function the way it needs to be. So I think at the lt4 km and tune the pcm for the mods you have!

 

Mail order tunes will always be on the cautious side when it comes to fueling, timing, and knock sensors.

I prefer tuning through the tune, you can safely desensitize a knock sensor while still letting it function properly for real knock.
