Question, my PE Throttle enable was at about 15% (0 -> 3500) and 5% (4000 -> 7000), how is that too high? Aren't those values low?

Thanks for the input, will try tomorrow.
Wondering why you changed the power enrichment EQ Ratio to 13.0? That's a lot leaner than my actual target of 11.8.
Thanks.
Understood, this is why I am having problems understanding.
Car is definitely missing at those RPMs/spots. Physically shakes back and forth/doesnt accelerate, AFR Spikes to 20-22.
Update,
Boost a pump, aux pump, both unplugged. Fuel pressure no longer dropping, misfire is still happening. See the attached log.

See around 35 seconds. Can't figure this out for...
Probably going to go with a Chris 1313 or Fore double pump system
I pulled the fuse for the aux pump, the problem is still occuring the same way. I will post a log later on. Tomorrow I'm going to take out the BAP and see what happens.
Tonight I'm going to pull the aux pump fuse, test it, if it continues, remove the BAP and see results.
Thanks for your input. Will update.
Hey Alvin, thanks for the input
I didn't even notice that. Upon further research, this fuel cut @ RPM seems to be a very common thing on these 5th gens, CTS V's, and SS's. See the link below.

TR7IX's @ Stock Gap, all plug wires are on & they are Taylor Spark plug wires. I see what you're saying on the screenshot with the No Fuel... but my wideband says otherwise and the car does not cut...
The BAP was something in the back of my mind but I was always thinking I was crazy... the BAP should be activating at 3psi, (if if installed wrong, 0 psi), the misfire always seems to happen at just...
I wasn't logging fuel pressure on that log specifically, on the other log(s?) I was. I don't really see any major dips in fuel pressure, WOT is fine, no issues, only this specific part.
Hi Greg, thanks for your reply.
I have not checked compression, but, this same issue was happening when I had my SBE 6.2 LSA in there, so I do not think that it is a motor problem. I do not...
Hello all,
My ZL1 appears to misfire / cut fuel consistently, but randomly.
Driving around, throttle at about 30-40%, car will misfire in the range of 2.5k-3k RPMS in 2nd or 3rd gear, AFR...
