hi everyone. well today i just noticed that under WOT, my boost went a little crazy on me today. it first hit about 18psi then tapered down to 14psi then went back up to 16psi. it just started happening today. (boost monitored on AP and boost gauge)

does anyone know what might be causing the random drop in boost at WOT?

mods are turbo back exhaust, cobb stage 2 91oct map, and pwr tmic.
