With the wideband afr sensor running WOT at 10.7(afr) while on 5th gear, I suppose there r still room for a larger turbo since the fuel supply is still way too rich?
Any input will be helpful, thanks.

The max rating for our turbos is 21.8 psi . Going beyond that mainly increases heat and does very little to increase airflow . In cool < 70 degrees F weather even at +5 psi you will be below the max , in warm weather you will def be over and mainly creating heat . This is why running more boost beyond a certain point with stock turbos has severely limited returns .
