When you give the car all the boost without even knowing it!
He tried to put it on a low boost setting but due to some waste gate trouble it went full boost and put that LS through hell! What should have been a nice cool 9PSI turned into an insane a violent 30+ and for a v8 that’s mostly stock that’s a lot of power that truck must have been well over 900HP! So at high RPMs that boost dial is useless because the waste gate just wouldn’t work so he was giving the car all of it! That poor engine, he really just went for it without even knowing it!
