A little grey with the black smoke under heavy acceleration normal?

Hey y'all I have an 08 with dpf/cat deleted,flopro turbo back exhaust,afe intake and currently running the sct livewire on the 120 tune. Is it normal/ok to see a bit of grey smoke mixed with the black when getting on it? It runs fine and does not smoke otherwise. Also blows a little puff of black when i let off the throttle and get back on it again. Any help would be much appreciated..thanks!

You're fine. It's probably not actually grey. Probably light black smoke just before the big puff of black comes.
