ECMlink WOT hesitation / DTC 0170 Log attached

[DSM AFFECTION]

My ecu keeps giving me code 0170 (fuel malfunction). Also under wot it hesitates. The best i can explain is as i approach 5k rpms (full boost 34psi) it seems to slow down, then pick up, then slow down throughout the rpm band.Still feels strong but its not all there. I have no boost leaks, verified everything. I was hoping you guys can look at the logs I've attached and tell me if you see anything out of the ordinary. Possibly point me in the right direction. I also wanted to let you know i have no front 02, only aem wideband right after my downpipe. Also 3.5 bar map sensor running SD.

Not sure about the fuel code, but it appears that your airflow is a bit erratic.

What should i look into to figure the issue?

Fuel pump (i didn't see it on the list)? Are you running just e85?

In tank walbro 255/ bosch 044 in surge tank. Dual maps e85/91oct. I only use pump ocassionally. I have a few more e85 logs. Earlier i logged a 2nd gear pull, it hit 30ish psi then sputtered down to 25 ish as rpms climbed. shift to 3rd and it held 30ish all the way through. It happens almost always in 2nd, more often than not in 3rd. Idk if its related but DTC 0170 keeps poppin up in link. Fuel malfunction. The car drives fine, idle is fine. However WOT there is an issue. Could my injectors be clogged from ethanol? A friend said my tps looks off in my log but i can't tell... ideas?
