ECMlink Leaning out before boost kicks in

[Vdubzr32]

ok so im leaning out way before boost kicks in the car bogs bad and AFR drops to 17.0 ish. just seeing 0 vaccum or 1 psi.

I replaced Fuel filter, Replaced fuel 255 Wally pump and o ring, pump is rewired and i am getting voltage, I conducted a vaccum check on the AFPR and im getting 1:1 Fuel pressure to boost, no fuel leaks, that im aware of. i gave PTE 880 and the were just service by Injector Cleaner flowing 840cc. I have also took fuel system apart and cleaned it to make sure line arent clogged.

what would cause the car to lean out before boost if not a fuel problem.

Thanks i can provide alog but itll show exactlly what i say. let me know if anyone can give me suggestions.

Your actual AFR only crosses your commanded AFR a few times in the log. Even when you are in vacuum the problem persists. There is not much idle time to check the combined fuel trims but at first glance it looks like the injectors are smaller than 840cc. To insure that fuel pressure is acting accordingly, you can install a barbed hose fitting with a pice of fuel line connected to your fuel gauge within your field of view while driving. With that said, Please follow this sticky and answer the questions so that we may offer the most accurate advice.
