If it changes so little that you can bolt-on and use, then it also means that it changes the parameters so little, that it effectively is equivalent to the stock header.
Remember, we have a MAF based car that works off of volumetric efficiency tables. Volumetric efficiency changes if flow significantly changes, which is what throws off the tune.
