You're at close to sea level, running 93, correct? Your manifold pressure is dipping down to -11 at some points, while at idle. You're only hitting 12.48psi max boost (stock is 13.54psi) and that was at 78% throttle. your manifold isn't getting the pressure it needs. now you just need to figure out why

This thread might help. seems to be similar issues. make sure your maf is sealed and seated properly as well. make sure you didn't lose the o-ring
