Reflash or Flashpro which would I need?

[1niceK20]

I have 09 Si still stock, but I have the skunk2 72mm manifold
and tb with takeda intake sitting at home. If I install them
and let the ecu cycle a couple of times to let the maf adjust
and get the Reflash will this have it running good, Or should
I just keep saving for Flashpro.

You will need the FlashPro so you can properly tune for this.
