Default Spring time questions.

I'm driving a 2003 Z ~ 30k miles. Only thing I have on it now is a diablo canned tune.

I'm probably going to pick up a Vararam in the next week or so. My question is about the throttle body. If I go ahead and upgrade, what size should I be looking at with the minimal mods I currently have? I'm guessing with the tune and intake I can get away with an 85mm? Last thing is about the tune. Anybody think it would be worth getting a custom tune done once the VR/TB is installed? Or is that just a waste until some more aggressive work has been done?

Thanks in advance for the input guys.

How do you plan to open up the inlet on the intake manifold to anything larger than the factory 78mm? TB is a waste of time without a better intake manifold, and you'll need some other things to go with those like LT headers at a minimum. Save your money for something that will actually add HP.
