Hello bro sorry for the late response.
Got this car imported directly, its everything is super fine condition, idk why today i got the culprit as the injectors installed were red colored tip with part number 23250-16160, which actually are designed for 7afe. I replaced with original 4afe injectors with equivalent flow rate, green colored tip with part number 23250-16150.
Issued solved, fuel average, low end torque, pick everything is fine now, just a bit knocking on sudden acceleration.
