so finally data logged with help from my friend who is a JB4 wizard, and he discovered that during the dyno it must have hit the peak boost safety and kicked down to Map 0. Which could by why I only put down 320whp. He said everything looked fine and I was still hitting 16.5psi on Map 5. He did a couple little tweaks to smooth out the power band and said it should be more around 350whp.
I'm hoping to hit the dyno again in a cpl weeks, hopefully for some better numbers
