Engine Mechanical problem

I have installed a brand new engine in my car the problem is with high feul consupmtion.
Check the engine on scanner at 5 different carges, nothing seems to be faulty. The carbon readings are below 1. New O2 sensor. Only yesterday found that EGI relay is not instaled in the fuse box, but the car run smoothly.

Hi there,

If the exhaust emissions are with in specs and there are no faults logged in the ECU. I would just get the injectors serviced if not done already and see how it goes, the engine may just be a bit tight and when it beds in things will improve.
