Mine might be in the low 12's but its not much leaner than that. I don't have an AFR gauge (well at least not NA I didn't) so I don't recall exactly since it's been over 3 years since I got her tuned.

I have a Ark Grip CBE, Motordyne Art pipes, and Injen CAI on my 09 nismo.. Will it be worth it if i have it tuned now ? Or do i still need a headers?

How much do you guys think will be my HP of i have it tuned now?

You'll probably get around 10whp from a tune, but also pick up drivability improvements etc.

I have a 2013 370z nismo. It is my understanding that the nismo already comes with a tune, I'm looking into the armytrix exhaust, will I still need a tune after the install? Thanks in advance!

Since i use torque android app at the dragstrip where i can monitor afr post run.

Car tuned at AAM shows around 12.5 during WOT for run.

Hills garage tune runs about 13.5

outside temp about 10 degrees warmer whrn i ran with hills tune.

Very similiar time. Within .1

Also my intake air temp is usually about 8 degrees hotter than ambient when driving at highway cruise, anyone know what their stillen g3 registers?

Nah rule of thumb is 3 or more breather mods. Even then you might be good but you'll start fuckin with the ecu by then.

We have similar experience with bolt on mods. We find that once you go past Gen3 intakes, HFC's, and Cat-Back Exhaust you really should do a tune. You will see gains from Tuning with just those three mods, but we highly recommend getting the car tuned if adding headers or intake manifold just to maintain AFR's (power gains are a plus though).

Yeah, you pretty much hit the spot. I personally wouldn't add headers or an aftermarket intake manifold either if I wasn't planning on tuning it immediately afterwards. Same rule pretty much applies to most sport cars.

Forgot to mention ported throttle body as well.

I am about to purchase Stillen Gen 3 intakes, F.I. LTH, and F.I. TDX CBE, and I'd like to get a tune (especially w/ lth) but I don't want to void my warranty... will this happen? or at least is it easily reversible in case I need to claim my warranty?

[seymore4]

It will not void your warranty. As long as you get the reflash cable with the tune you can easily remove it and go back to stock anytime you want
