Yes, if a chip is done properly then it will probably have new maps for ALL variables (fuelling, igniton, and on some turbos the wastegate control valves) simply to optimise the settings - some parameters may not be different - depends on the engine etc. and how good the original data was.
However, a few years back in England, some aftermarket chips for Ford models from two apparently unconnected sources were compared .. found to be identical and one sued the other ... BUT it came out in court that both were actually identical to stock ... was then a police prosecution of both for fraud.
