my problem is that on my afc its about -3 all the way across on the hi throttle side to get rid of knock and even then it all doesnt go away. but if i run it leaner taking out fuel my car stutters and bogs when i get up into the 4000 rpm range. my o2 readings are right at .94. it is a 1g. i have all my fuel mods with the gm maft blow throught setup and im running 750s with an afpr, and a 255hlp. i have my maft setup for 700 cc injectors cause my low trim is pegged at 118% and wont move. the manual says to richen up the entire fuel curve set it to a lower injector than what you have. i need to know how to get rid of my knock without having my car stuttering and bogging. n e ideas would be appreciated.
