B20 Vtec Problem With sensor map lost power on Wot

[gibonek20]

hello i have a problem for a long time with my honda this is a honda civic mb6 b20 vtec this is the specification
engine b20 vtec pistons ycp 84.50 head b18c6 camshaft b18c4
intake manifold skunk2 Pro
throttle body 70 mm tegiwa
intake 70mm
injector 550
exhaust header toda 4-2-1
exhaust 2.25
symptoms are lack of power despite the correct afr I have tried various ways but I still can't find a solution problems symptoms are jerking lack of power and shooting in the exhaust and loud engine work the car hums does not go despite the correct afr set, the idling speed is stable tps I also checked and it works correct and was set but one symptom that I noticed in the logs concerns the indication of my map sensor, at wot my map sensor shows values sometimes from 0.0 psi 3459 rpm tps 101% 3780rpm Map shows -0.1 psi 4000rpm Map -0.2 psi 5000 rpm map -0.4 6100 rpm Map -0.7psi and it seems that then the engine is working normally, should it correctly indicate the value of the map? because I noticed that when the engine starts to run like shit and loses power, my map sensor behaves like this in wot TPS104% RPM2506 MAP 0.1 PSI RPM2682 Map-0.8psi RPM 3029 Map -0.0 psi 3378RPM Map -0.1 3517 RPM Map -0.0 psi PSI RPM3735 Map -0.2 psi and here I have a question, is it showing the value of the map sensor -0.0 psi, is it not a loss of signal from it? Because I suspect that there is a problem here, here is a video of the car slowly turning up as if something was holding it
