Mod question
I have the 5/16th spacer, z-tube w/ K&N filter, and borla exhaust. My question is does the G35's stock ECU update the change in the Air to fuel ratio automatically? or do I need to some how reset the system? or is it not enough to be worried about?
I'm planning on getting an Osiris Tuner but with a tune down the line. I was just worried that my car may be running to lean.
Thanks sry for the noob question.

With that setup, you are most likely running lean. If you have an 04.5+ car, the ECU's don't seem to be able to compensate enough without some sort of tuning. The 03/04 cars seem to do a bit better, but they still improve with tuning. A simple dyno with with an A/F reading will give you a close ball park figure.
