Hi Im planning to get fpred and custom tune soon. My goal is 400+HP without cams and pump gas. B4 do that, I would like to buy some supporting mods which are able to hold boost 23-26psi all the way to redline.

Here is my question.
Which mods are great to support holding boost at red line?
Which turbo holds more boost? Red Green BBX Dom??
It seems that BOV and WG are helpful. Which Bov??

I researched some threads and Dyno charts but i cant figure out.
Help me.. Any recommandation and feedback will be appreciated.
