ok still got a problem. heres the next log after the hoses have been changed to tighter hoses.
is there a way via the log to tell if all the injectors are firing. because it could be possible that I didn't make a good connection when I extended my injector cable.

narrowband o2's, 0mv is lean end, 1000mv is rich end, they would normally oscillate back and forth, they were just sitting lean.

grab a screwdriver and listen to each injector, should hear it clicking.

ok ive checked the injectors and I can hear them clicking. but it still feels like its missing. could it be spark plug gap???

edit is the right o2 sensor drivers side?? cause that's the side that's lean. atm

Are you using standard vy flash PCM or the l67 ecu that is memcal based?
What tune/bin file do you currently have running in the vehicle?
If you have changed top end, did this include injectors?
If you changed injectors did you update the injectors data in the calibration, if not it will be running very very lean.
