2004 gsxr 600 sound like misfire under 4k rpm. i need helpTake a video and load to youtube.
I hade the bike for like 6 month. But i hade ride it before multiple time and no issues prior. But ill look on the unplugging the sensor to test the ecm i already put a new one and didnt make a difference. I thought is call ecu but is the ecm what i put new as well hunting for the issueMight be time for a compression test. Did you just get this bike? You might want to just check the cam timing as well. If someone else got in there and tried to adjust and made a mistake, it can cause weird issues.
The other thing to try is unplugging sensors one at a time to let the ECM insert the static values. It could just be the ECM doing the right thing with bad data.

So any idea why at take off it bug out (misfire) almost imposible to take off and now even more questions why it have 60 psi on all 4 cylinder but ones it pass 4k rpm it have lot of power like new?At 4k rpm, the air doesn't have time to leak out before ignition.
I did and also replase the sensor and since i was in there i replace all vacuum hoseI would have to put hands on it and perform some diagnostics. Also at low RPM, the engine has a higher vacuum. Could indicate a problem with the IAP hoses/sensor. You have to do the diagnostics.
