Weird boost loss only in 2nd gear

I've noticed that sometimes when I am going hard through the gears the boost in second gear goes to 18psi and then dips to about 15.  Every other gear holds at 18.  91 octane with stock TC intercooler, 3 inch downpipe, 3 inch magnaflow race series ler.  Same thing happened with the stock exhaust though.

Any ideas?
