Looking to have stage 2 map as well, your spec similar to mine but I have 3"APR down pipe with sports cat and full milltek system. Mine running APR map which is pretty awesome. Will be interested if stage 2 map would benefit from larger injectors.

Your fuel trims will be way out and could be washing the bores under load conditions which can make the oil weak, the bigger injectors need to be mapped in just the same when going for a 4 bar fuel reg.  If you log blocks 32 you will find your fuel trim MULT/ADD adaptions are hitting the upper limits.

Your best bet is leave them until you take it for mapping then you can get them setup correct, Get the map changed the fitting the injectors.  To change the AUM map for bigger injectors is only a 5 min job, just need to adjust the 1x1 KRKTE - primary fueling constant map for the 380cc flow rate then the whole map will be spot on fuel wise.

so am i doing major damage to the car as there aint no roughness ectect i got vcds lite can i do it opn there?? aint dave iow running different injectors and maf without map changes??

Not the same ecus..

AGUs can be offset with bigger maf % to go with injectors.

so am i doing damage am i or just overfueling??

Overfueling which can wash in to the oil and cause issues, the power will be less as you will be running far to rich top end when the car reverts to the lambda protection maps.  There are no gain to be had by fitting bigger injectors / 4 bar fuel reg without making map changes.

The stock AUM injectors will flow to a little under 265bhp maxed out.
