Hello everyone I have search all over for a answer to this and really couldn't fin anything. This is what is going on. I will get into boost 13psi and it is good runs great. But when I plug in my scan tool I found that I have knock-yes knock retard 0. Even when I am in full boost at high rpm knock yes retard still zero. I did swap my knock sensor yesterday and as soon as I did knock was no. But today its yes constantly. I really don't know if maybe this one took a dump or not. But I do know that if I hit more then 16psi it will backfire and I will get 6 to 9 degrees of retard. I found this out tonight lol. damn boost gauge hose popped off. Other than that heres what I could get at idle from the scan tool
rpm 775
intergratr 128
blm 129
iac 24
tps .44
temp 169 yes its cold. It is almost winter
load/lv8 43
airflow gm/sec 6
I don't know if this will help anything but any thing helps
