Correct me if I'm wrong but torque management shows up as spark retard? Have no idea how you get more retard from less timing?

So I remembered something that I ran across years back on a different swap. The 96-02 L30 305 Vortec and OBDII LT1, LT4 and L99 engines all use the same knock sensor and it is different than the 96-02 L31. At this point I am thinking of swapping to the L30 knock sensor or properly torquing it to 14 ft/lbs. I seem to remember an overtightened knock sensor becoming too sensitive.
Over tightening will do it and ruin the knock sensor.
Strange how OBDI knock sensors match engine displacement? Can you compare a 305 cal/bin/tun and a 350 cal/bin/tun? In EFI Live there's a ton of Knock sensor settings.
What's a HP Tuner file extension?

I believe they are .BIN files. That being said I have a EFI Live .TUN file for both the 305 and 350 Express vans.
I don't suppose you ever get to 4400rpm in 4th... 2nd and 4th gear in the 4L60Es run the rear planetary gearset, and it's possible that this particular trans may have some needle bearings starting to wear. How many miles on it? Also, does it make any gear noise in reverse?
