I am also doing an oil cooler and spacers, but those will be on before the rest and aren't performance mods (though i guess the oil cooler allows the car to perform).

If you're planning on doing the CAI and pulleys and more, though, def good to save by doing the tune later, although a friend of mine was overheating on the track because he was running too lean and that forced him to get a tune. I also heard that the first Uprev tune costs the most because they need to register you and stuff. Subsequent ones shouldn't be as much.
