My injector DC is in the 95% range and im have time retard problems its pulling about 4 degrees could this be a cause from the high DC %???? also the short and long injector pluse width is dipping in to the 108 -115 most of the time not coming off those numbers. could this be caused by the DC????

 

Sounds like your leaning out. My setup was giving me the same thing. I upgraded to SVO 30lbers and my DC went from 100% to about 80% at WOT and my knock went away.
