Default Gas=beer help

Engine = b20 with ycp high comp piston vtec b16 head with GSr cam.
Engine running fine, idle set to 850, timing 16 degree, but just idling the car for 10 min it burn thru 1/4 tank of gas.
Why so much gas used.
Exhaust are brand new, 3" cat back, and stock injectors. My 440cc runs rough, fuel pressure set to 37 lbs, 255lph fuel pump.
Need help to trouble shoot high fuel usage

No car present, only an engine. Moved to Tech/Misc as this isn't about a car, only a motor in some mystery vehicle.

You are burning a ton of gasoline because you are giving the car at least double what it should have it sounds like. original injectors 240cc, now 440cc, original pump probably 130lph, now 255lph....needs to be tuned...
