Default knock retard question

can anyone tell me what could possibly be be some of the causes of me having 8* of knock retard on a regular when the car warms up? i can be idling and just cruising and it stays at 8. if i stay at the same throttle sometimes it will come down some n the car will speed up n run alot cleaner. when i just give it some gas it will come down some but i just dont understand it. with my scanmaster and datamaster both are reading 8*

LT1 knock modules are ridiculously sensitive, alot of us just swap over to the Lt4 knock module as it isnt as sensitive and really wakes the car up...

might have to talk to Ion about getting your re-tuned. was your tune done after the valvetrain mods? if not that would cause what you are talking about.

i bought a LT4 km long before the mods. so i assume its still in the computer i would hope he wouldnt have any reason to take it out. as far as the tuning i got it tuned after all the mods. its just strange cause the car has 8* alot. i can be puttin along n once it goes down a few degrees the car will accelerate like i gave it more gas
