So, battling fuel pressure problems right now. My AEM is adjusted for max fuel pressure and it won't go above 42ish at idle.

So as I believe Shane suspected, the car appears to be bleeding fuel back through the second pump. Doing some testing now, but might be getting a check valve for the second pump soon.

Need to bump fuel pressure so we can reduce load as I was hitting 330load and boost cut (319 load) on pump gas at like 24psi.

So we are making it so the load is hopefully 270ish around there by changing around a lot of stuff. (injector scaling, MAF/MAp tables etc)

Not going to lie, I doubt I am going to PG. Especially since work is really crazy. I am kinda bummed but frankly I don't want to go until the car is working fully. I will head out to RF or BIR at a test and tune day when its done if I don't make it.

Still going to try and make it but not looking good now.
