APR X-1 Possibly shorted?

Long story but here it goes:

Under a load, only in 2nd-6th, at wot, the truck will completely loose power, backfire, have nothing. And if I keep my foot on floor it is just at a complete loss. If I like feather the gass, it will come back at 100 percent so hard it will screech the tires.

I have checked fuel pressure (good), new spark plugs, new coils,new vvt solenoids, new upstream o2’s, the connection for the o2 simulator is right, cleaned the maf sensor, cleaned the throttle body, checked for any broken/melted wires, unplugged the pedal commander. Went over everything.

With the x-1 plugged in, I was getting two codes. P2240 and p2241. If I’m correct bank 2 sensor 1 is oxygen sensor closet to the battery driver side. Which is new with no melted or broken wires.

Now, if I unplug the X1, and use oem ecu, everything is fine. I run the dog piss out of it no problems.

Im guessing the x1 finally took a crap? Any OG’s ever heard, ran into this problem? Anyone locally have a x1 (N/A) I could use to make sure mines crapped out. If so I guess it’s time for hp tuners. ‍♂️‍♂️‍♂️
