cutting out in boost
iv been chasing my tail on this one. cant for the life of me figure out whats going on.
its a 08 5.3 with headers 222/222 cam and d1sc procharger with 3.55 pulley, has bosch 650cc injectors and walbro 450 every time I get up to around 9 psi the truck starts cutting out and the wide band goes crazy when it starts cutting out but from what I can tell in the log its pretty close before it stats its shenanigans.
I was thing maybe the gas was running to the back of the tank where the pump couldn't pick it up so I filled it up and same story, tried a power brake, no luck.
I think I'm running ngk br8 plugs, cant really recall. one thing I didn't do is gap them, just remembered I didn't do that. could I be blowing the spark out at 9 lbs?
here is a tune and log
