i wouldnt say crank trigger, cuz he can make it to redline, its a boost dependant issue… id say map sensor is probably bad, or maybe an injector is sticking… do u have a wideband that u would be able to check why it chokes, is it too much fuel or not enough, my guess would be its totally cutitng out, meaning the map sensor isnt reading the extra boost
if it was a boost leak ud still make it to the psi u want just wouldnt have teh cfm to have power there
