ok so i am pretty clear on how knock is measured on these cars and how to determine if it is real or false knock and i have come to this conclusion, i can only run about 16psi w/o knock and i am getting some false knock on shifts. what i didnt realize is when i ordered my turbo i got the hd actuator and it only goes as low as 19 psi even with my manual boost controller turned down and the rod adjusted out. i think it is knocking b/c my fuel pump cant keep up, i have a walbro 340 and im gonna put it in soon but should 19psi be ok to run without alky w/o getting knock?? also i hit recall on the scanmaster last night and it read 770something and 0.0kr what does it mean when it records 0? wouldnt it just stay blank the screen like every other time it doesnt knock?
