Another Knock Question

[kiknturbo17]

Hi, i need some info. My car is gettin tons of knock and im wondering what i can do to tell if its phantom knock or if its actual knock. I have a full 3" exhaust,uicp,o2 dump and boost controller set to 15lbs on the 14b...Now i have stock a stock fuel system,but pretty much anywhere past half throttle my knock shoots up to a full 43 counts...I really dont think its that bad. I was thinkin maybe my o2 dump would have something to do with it but any of your guys comments would be appreciated.I know there are other topics for knock but i didnt really see anyone with an o2 dump talkin about it.Thanks
Joe

Its phantom knock. Try running some Seafoam or MCC through and see what happens. You probably just have a bit of carbon in your combustion chambers.
