i did not download your KP but KRKTE should be at 0x18C6B
Have a loot at your part throttle value in block 032 to alter krkte until 0% difference
which injectors (part number) are we talking about?

You have to decrease KRKTE with bigger injectors, not increase it !
Try 0,0726 and adjust with fuel trims.

Just on a side not the "green top" 440cc injectors dont work well with 20vt's i went to use these and opted for genisis 550cc in the end, green tops are like a water tap compared to the genisis 550's. you may struggle to get a good idle and "off throttle" fueling

Do you have an AFR gauge/reader?
What else has been done to the car that could cause issues??
