So I have been tuning my 00 silverado, LQ4, 80lb injectors, gt45 turbo. I have it drivable, but it picks up knock randomly. Sometimes it runs great, and sometimes it shows 8 KR. Doesn't matter if its in boost or not. I attached a log. Truck seems to be fine, but you can feel it pull timing and absolutely kills power. Wideband shows its rich, still in the progress of tuning it.
Any input is greatly appreciated, I am still learning how to tune :cool:
I sorta remember you're user name and had to click back to your previous thread.

If you still have any knock codes or pending codes, it will cause the knock retard to pull the max timing allowed in the tune which is 8 degrees anytime it thinks there is knock. If the sensor are good and known to be working, disable the codes to prevent this issue, the knock sensors will still work.
How has the tuning come?
I plan on doing an LQ4 tune with similar parts, although many will say the gt45 is a bit small for a Lq4, its what I have myself, as well as 80lb injectors. ill probably get an s480 or something similar for mine later though. currently the gt45 is on my ls1 and it spools nice!
Did you sort out the sparks tables to control knock?
