"Boost Spike" = Boost exceeding a set target for a instant.
I.e Car tuned and set up for 15psi....But it spikes momentarily to 18psi (usually a midrange over shoot).........
This can be bad if the car is on the verge of detting @ 15 psi......that 3 psi spike can induce leaning out, detonation and pop your engine.
