Hybrid turbo upgrade selection & general tuning question

Interesting. My experience and what I've heard is that the boost rises with a more free flowing exhaust due to less back pressure, and would need a FCD. But if yours isn't then you I would imagine you are fine. I run a full RB turboback exhaust and I hit 11-12 consistently and it bleeds back down to 8 with only the stock wastegate for control. It even will creep higher in 4th and 5th at certain RPMs. I am running a FMIC.

FWIW I would love to run a BNR stage 1 at 7-8psi. If my turbo ever has problems then I will probably do it. I'm not looking to make big power, just enough to get out of my own way.
