Bad hestitation at higher load Mustang

Hi

maybe You will get some idea...

Car was driving year or so without any problems. It's turbo mustang with cams (my personal).
Since 3 days he hestitates strong at some load, about 0.8-0.9, sometimes less. I can close rev limiter (so looks it's not crank pos sensor) when I'll accelerate with throtlle at 1/3, but once I go past this, it makes like fuel cutoff, spark blowout or so, but, fueling is there and is correct, this car is dual fuel and second fuel makes this same. I disconnected PCM of second fuel system, same. I tested also without boost, same. Like tcs kicks, or rpm limit hit... I changed ignition coils and spark plugs, still problem. Datalog from second fuel PCM says it cuts fuel injectors, but he can cut also spark. I have missfire disabled also due cams. 2 times after it hestitated, he shuted down car completly, I was slowing in gear, I switched off ignition, then on and he didn't fired up. When I stopped car, off, on, then it started.
I have also tachometer for rpm conversion, but I removed it too without success.

I have 2 ideas, some torque managent makes this ( I disabled all TQ management for test I could without success) or my PCM finished life or some strange electrical problems. No DTC in HP and in IDS.

I attached log from oscilloscope and log from HP and tune.

Let me know if You have some ideas...

Thanks.

Hi

After another hours I traced the problem. It was ABACO MAF failed... another $....
But after it I realized there are some importand tables missing to tune speed density:)

I am not a fan of those MAFs
