You have no reason for a tune of any sort right now. The factory ECU is perfectly capable of learning, Ive been running my SR with a few more mods for 3 years at 13 psi on a fully stock ECU. The only time you will need to tune is if you change injectors, MAFS, or your cams.

Personally I would skip the Sard unit, and go for a Nismo direct fit, it involves less hassle. Unless you plan on switching to a top feed fuel rail in the near future, the sard unit isn't really necessary either. If I had to spend your money for you, Ide look into a high flow fuel pump.
