I have tuned from rotofab to cai. If its tuned on the nose, there will be lean spots, if it was tuned with a AF buffer you might be ok but it will still be fatter and leaner throughout the curve. You’ll be better off keeping the cai in that case...No doubt. If you retune it’s a different story.
They are really designed to be interchanged against the oe maf curve, once you tighten up on that with a tune, it needs to at least be validated. IMO
