That would make sense. If by stroker you increased or decreased the stroke of the engine, then that would change the displacement and mess around with the amount of fuel the engine needs. So it could be possible, but don't take what I say to heart i'm just guessing.

chromius_e30's stroker didn't like 19# injectors at all.. he went with smaller ones. 19# is likely simply too big

19 lbs injectors is alot for a e30 2.7 ...you will need to adjust the afm to get a better throttle response...what is happening is that you are getting too much fuel...you can also try to unplug the ecu for a while just so it can calibrate itself to the new fuel injectors...

What CR is your motor? You need a chip developed for the higher CR that strokers usually have (10.2:1). Did you also change the cams?
I have developed a chip that works perfectly if you have a 10.2:1 CR, cams, and 19# injectors. Don't fool around with your AFM ! *no-no* If anyone tells you to adjust it, they are giving you very bad advice.

Adjusting the AFM is the poor man job of getting the right Chip*th-up*
