With the small stock intercooler (I'm assuming that is what you have) on a 930, factory boost gauge and no knowledge of your AFR at the higher boost I think you are playing with fire.
If it were my car I would install a mechanical boost gauge before changing springs and dyno dyno the car after the change to get a picture of your AFR.
