Just a quick question.
What is the normal duration of the boost spike that we all talk about.
Is it short(1-2 seconds) or does it last untill near redline then the boost
drops to the 15-16 psi?

Spike is a very short, not even a second, burst of pressure in the system before the wastegate can react and bleed off the necessary exhaust gases. It is common with a turbine that is way to small for an engine.
