Vitz 1st gen with 2zz swapped

Vitz 1st gen with 2zz swapped

I have bought the Toyota Vitz recently. I has 2zz swapped with 6 speed LSD c63 gearbox. The car is working well but I am facing a biggest issue in the car and it has very poor fuel efficiency. The car gives around 6 to 8KM and max 220 to 250 in a tank with few pulls only. I have serviced the car many times but the issue is still not resolved. I have come to know that its fuel average is normally 10+ but I don’t know how? I have already made these checks Plugs good, No error codes Throttle body serviced Used Injector cleaner using mixture of high octane and regular Wiring was fixed with few new clips and idles good as well. As I understood the issue, it’s due to its 17 inch alloys and has low grade tires that’s why I am facing this problem but it should not be so much. As I owned the car few months back and according to previous owner the fuel average of the car was 12-14 km. But, I will be satisfied if I get 10 only. As the car is installed with 6 speed transmission and I mostly used 2000 to 3000 rpms as well, so I think it should give a best average but unluckily not happening so. Plz give me suggestions and guidelines.

First be sure no mods being done to engine. Specially aftermarket injectors, headers etc.
Hook it to a scanner and share logs here.
