Similar engine same turbo ,no i dont think 225hp is possible with any reliability anyway.
I found the std turbo suffered with boost creep around 180hp decatted, and with fmic and decat id think 200hp-210hp tops but how much psi.
Ive upsized my turbo internally +2mm on turbine and still near boost creep at 2850mb ( hitting 20% vnt means boost creep really)
If serious id go the way of gtb turbo, boost is not a problem then just pick your hp.
I did 191whp last and that was with water methanol aswell.
Already mapped you may notice little difference after fmic fitting, mapped again after you may gain a few hp, as said above you would need to know if your boost temp is hot now, if not you may gain nothing.even at 24-25 psi my temps wernt that high anyway especially with shortish throttle blasts.
If you search jtd fmic im sure i did a few logs pre and post fmic to show gain in maf airflow and i think jsjtd and tribesman and yanko have similar data somewhere on here a nice graph is in there or a gtb turbo thread temps and airflow.
