Obviously the car will run better with tune and gain power but your talking about $600 dollars a tune for just N/A mods. If you were F/I, you have to have a tune to run the car.
Most people do not go with the headers as most already know that they don't do much. Only proven header is the FI LTH. Other than that most have ran the car with I/HFC or TP/ CBE without issues.
But would you pay $600 every time you added a bolt on? All I suggested is that he get all that then tune. Not everyone has $$$$ disposable to shell out for a tune after a $300-500 mod was added.

You can do enough with the airflow on a full set of bolt-on's to bring the car out of the range where it can adapt and run lean. The Z runs a very adaptive ECU, but it can only do much. We've seen the trigger being the combination of the headers and removing the factory cats.
Yes, agree with your position of get the mods you're going to do, then tune for maximum $$ savings. But remember part of what you're paying for in the tune is the license itself, which UpRev runs $300. Anything beyond that, and you're just paying for dyno and tuning time, so it gets less expensive.
If you're really wanting to geek out and go to town, you can also get the Tuner version of UpRev, and you can tweak most things yourself. More expensive route? Absolutely.. but a lot of enthusiasts enjoy learning the details of tuning, and UpRev's tuner version will do just that. It's not the full package that a tuning shop will get, but you have enough leeway to hang yourself if you're not careful.
