Pretty much full bolt, short of a custom turbo manifold. Using stock KO4:

AEM CAI
PG TIP
Corksport divorced wg DP
Corksport RP
28X7.5X2.5 FMIC
Stock BPV (went back on after Forge started leaking)

This setup does push the turbo pretty hard at maintained high loads, with high EGTs I've documented. Acceleration runs are no issue, just holding high load for a long time, like a high speed highway run. AFRs are totally safe and no other issues are present. The car is a pretty good rocket like this.
