Cuts off at high RPMs

[hecZ26]

Well, I've been having this issue for a long time. I'm fed up with it, feel like I can't fully enjoy the 3500 swap. I drive the car a few times out of the week but got used to the issue. Its been there since the 3500 swap was done. Engine breaks off bad on high RPMs and heavy load. Did a log a while ago and noticed that it doesn't go past 4k rpms. (my tach gauge doesn't work)

-Car has a new walbro fuel pump
-new fuel filter
-new (used) maf
-new plugs
-new plug wires
-coil packs good / icm good


Maybe this log means something to somebody. Car cut off a few times during the log.

Also found this thread, I have the same issue and made me think that maybe it has to do something with the park/neutral switch.

Any suggestions?

your fuel trims look to be way, way off but that is one of the weirdest csv formats that I've ever seen so I may be interpreting it wrong.
