Default Tuner wanted, fuel consumption GDA WRX

My car is a GDA 2001 JDM WRX bug eye 4eat auto.

The fuel economy is not as it should be (around 12.55 litres per 100km)

I was getting 150km to the 1/4 mark before easy, now its more like 120km.

On recent MOT its failing emissions as its running rich and I can smell fuel when I park it and get out the car.

Its got 600cc injectors, K&N typhoon CAI, Bigger TMI, Silicone intake, up pipe, down pipe, extractors which where all fitted after a rebuild 5000km ago.

It has a HSK SSQV which was on the car when it was getting good fuel economy.

Its been tuned before but not finished up 100% (long story). Its running open source and I have wideband.

Can anybody take a look at my logs and see if they can spot anything obvious. It idles perfect and starts first pop every time.

I will include a capture of learning and codes (rear O2 is out because cat is ruined from running too rich before)

Sorry I cant seem to see where to attach files on this thing so I hosted them there.

If any tuners out there with references see something obvious and can help I can pay.

Thanks

Forgot to mention.

It has new plugs gapped to .028, new coil packs.

It was backfiring on liftoff after WOT before I did this.

I will change MAF if somebody thinks its a likely problem but as stated it idles super smooth and has no real hesitation anywhere.

It seems to hold boost fine and I can't find any vacuum leak but that does not mean it has not got one.

Thanks again.

Check for leaks. Vacuum and pressure leaks

Might seem a silly question but.....

Where are the most common Vaccum/Pressure leaks?

If there is no leaks in any place a hose is fitted with a clamp would that take care of everything or are there other places such as the intake manifold having a hole in the gasket?

I will check where the SSQV is bolted to the TMI but other than that is there a place thats easy to miss?
