I have a Pro M 87MM MAF, filter, and 42lb injectors for sale (lightly used) right now. That would be a perfect setup for your application.
A tune is required when you change injectors sizes. Using a calibrated MAF will allow you to run and drive the car but any time you change injectors (and you'll need bigger ones!) you should get a tune or at least a chip for starters.
If you want to start, run, and break in the motor with the stock MAF and injectors, that would be a smart idea. Then after 500 miles and before exceeding 4800rpm and 10psi boost at the same time, upgrade to a new fuel system and get the car tuned.
This approach will allow you to run the car initially on the stock tune and injectors making your break in safer and more effective as the first 30 minutes of run time are the most important part of break in.
