Hello folks, I'm in need of some help with my fuel pressure. I have a custom turbo kit, DeatschWerks 265 fuel pump, a FPR with return line.
Injector duty is at 80% only at 5500 rpm with a crazy AFR. Some datalogging to look at. Currently in a tune, but cannot figure out what is wrong.

What exactly is the problem with the fuel pressure?

Not sure if im getting enough, or too much. Under boost is near 14.5 AFR. And that's only on a 3rd gear pull up too 5500 rpm with the injector duty at 80% already. Vtec and cam is at 0 degrees for now for tuning. If that is being tuned too, the injector duty will sure go higher.

What is the fuel pressure doing when this happens?
