aem fic on an N/A motor?

[BEEF]

I've been doing some thinking of what my next step will be with my car. I don't think I want to go boosted and thus have been limited by what can be done. I have done most of the bolt-ons already.

I wonder, are there any advantages of fuel management on a non-boosted yaris? Can you control timing? Am I pissin' in the wind on this one?

Currently, I have done:

-AFE SRI intake
-Weapon-R header
-2" mandrel bent exhaust with straight through muffler

(not for power)
-White line sway bar
-HHR springs
-MI short shifter
-MI shift extender with metal cable bushings
-added a tachometer

I am planning on doing the lighter crank pulley but not sure where to head after that. I have been told that lighter wheels would make a difference but I kind of like the look of mine at least for now.

any suggestions would be appreciated.

Thanks
