I got a question.... How does one know if the turbos are flowing equal amount/lbs of air into each bank?? With no common plenum, is it a pain to tune?? Would a common plenum or intake cause pulsing problems with each turbo??
I have no idea about any of that, so I'm asking for my own...
Mine did that the other day, but its topped off. Happened right after a hard launch not sure if that means anything.
I'd check it hot and cold, like Jason said, could be a sensor. It's happened before.
