Injector PW Bank going low only on one side at WOT

[PAT WS6]

For some reason the car leaves fine and in the middle of WOT at high rpm we have a side going real lean almost shutting off the injectors (one Bank). Both banks are fine at 25-35 Pulse width at WOT and then Bank 1 will drop to .9 causing car to pop and miss

We are running 160# injectors maxed out. Car is on Alcohol. 50psi base pressure 1:1

Any help is appreciated, Attached is Log in frame 3:17- 3:18 you can see the problem

What is your fuel cut off RPM set at? Right at 7000 RPM it looks like its cutting fuel then kicks back in under 7000.
