50lb injectors and stage 3 pcm

just wondering if this would work. i know the 60lb injectors idle fine.. but run way to rich and kill plugs.. would 50lb work? i got the stage 3 gm pcm and was wondering if i culd run a little bigger injector on it.

If I remember correctly there was something about the 50s that wouldn't work. I can't remember if it was a harness thing or what.

the gm stage 3 pcm is locked.. no way to tune it... thats why i'm askin. no big deal if i can't up grade injectors. i was just wondering. i think someone on here was running the pcm with 60's and killed there plugs.. anyways.. no big deal.
