so im trying to chase the demons in this car. I got it idling ok and did my cruise tuning(combined ftadjust). Then when I started to get on it the car goes really lean the second it hits boost of any kind and in any gear but if you ride it out the fuel kicks in and it takes off.... I tried messing with VE table but it is not the problem(yes I know its not anywhere perfect but I cant work on it until I get it to give me fuel)

The other part is I smell fuel but there are no leaks that I can tell and it only does it when mashing the throttle. If it was spark it would usually go rich not lean I would think.

Clogged fuel filter maybe?

anyway I attached a log if there is anything that stands out I could use the help
