Hi,
I have a 370z Nismo with Injen CAI, ERZ HFC and Invidia Gemini CBE. Recently got to the dyno and my numbers were:
312 hp 255 tq
12.36 AF/ 91oct

When the tuner tried to lean a bit the car, it losses hp so he went with the rich route. What are my options on getting more HP staying NA?

Really if you remain NA their isn't too much more you can do without it costing a lot of money. You can loom into the Z1 400 hp kit, look into 1slowZ build thread and a few other members but our motors aren't the best remaining NA. You could go FI :X

I agree you are pretty maxed out without some serious $ in upgrades.

That's pretty lean. Most tuners try and keep WOT AFR in the 11's

This was just discussed a few days ago.

When i received the Etune, my car was 12.84@7k... Now it is at that number but for NA Im sure is 95% on the safe route. Or 370's run richer???
