Stay NA and you'll be fine. The ratio of breaking vs not is probably 5% to 95%.

I installed a K&N Typhoon intake and filters, and my check engine light has been coming on ever since (Code 0300 - Random cylinder misfire). The dealership looked and it said the car doesn't feel like it's misfiring when they drive it, plus they didn't find anything wrong with that could cause this problem. They said Nissan will tell me to take off the intake before they do any other tests since that's possibly the cause of the code.
It's going to be really annoying to switch out the intake, do you guys have any other tips? Do intakes cause codes to be thrown?

bump

We have not seem random misfire codes from installing our intakes, but I cannot comment on the K&N as we do not see them as often. Anything is possible, but for an NA application it is a little odd. No other codes other than the random misfire?

Do you have an aftermarket clutch?

have stillen g3 laying in my room, just picked up the car yesterday. has under a 100 miles on it, should I wait till the 1,000 mile break in or would I be safe to throw the intakes on right away?

There is generally very little or no break in period (depending on who you talk to) on most newer motors. I don't see why it would be a problem to install your Gen 3's right away. Could be beneficial to have the ECU learn the intake a little sooner as well :)

Right now I have fast intentions non-res CBE and R2C intake only, but about to pull the trigger on:
Z1 test pipes
Z1 intake manifold
Stillen underdrive pulley kit

Should I get a tune? Also what is a rough estimate on HP/WHP?

Yes. That's a lot of breather mod changes

You should at least have it run on the dyno to check A/F Ratios. You will most likely need a tune and would definitely benefit from it. If you upgraded to STILLEN Gen 3's you'd probably be in the 330 whp range (if on 93 octane).

Car came with a Nismo CBE (I'm guessing it's a dealer install option from Day 1 - It's on there like factory)

I'm looking into Berk HFCs and I dunno what intake to go with yet.

Do I need a tune?

It's not absolutely required, but yes. You'll get much out of your mods if you tune the car to them. You also get some pretty nice secondary benefits. Wait until you have the HFCs and intake installed. No reason to get tuned until you have all your bolt-ons done. Go see JTran, they'll take care of you.

Mods Currently On

Motordyne M370
Motordyne ART Pipes
Akrapovic Evolution CBE

My plan is to go FI but thats not happening anytime soon (7AT - rebuild transmission and all)
Should i get a tune ? Since i have the m370 manifold should i also get the stillen gen 3 just to compliment them ? What is this throttle bodies ? Do they provide NA gains ?
My AFR must be messed up i assume

(i should probably make a single thread for myself as i keep asking questions in every thread)

I am probably too late!!!! However, whenever you bought the M370 you should have had a tune lined up as well. I would not have bought that part without everything else due to the fact that it practically requires a tune. You also do not have cats due to the ART pipe. You, my friend, desperately need a tune :D.

Hey guys am getting a NISMO CB for my z do I REALLY need a tune? Would a cat back make the car run rich or lean cus that's my only concern (very bad experience)

You won't lean out with a catback only. No tune needed.

Should I get a Tune?
 

Hey guys, I am currently running STILLEN G3 Longtube intakes, ARK GRIP V2 CBE.

Every now and then i'll drive it hard and maybe get a p0300 code and just do a ecu reset and it'll go away. I figured it had something to do with having a more lean AFR while on the top end.

I just purchased a Tomei EXPREME Ti and going to mate it to a motordyne XYZ testpipe modular Y-PIPE and also got some BERK HFCs on the way as well...

My question here is will the ECU be able to adjust this time or will I definitely be running too lean and need a tune?

Thank you.

You would see a definite performance improvement, the general rule is 3 air mods for a tune and you have reached that level

Currently have Gen 3's along with a NISMO H pipe and mid pipe mated to a resonated axleback from Topspeed. Car feels way livelier and faster than stock, AFR on Torque Pro fluctuated from 11.8-13.3 on WOT. Not sure if that's accurate or good.

2 bolts on do I need a tune?
 

Stillen gen3 and art pipes do I need a tune up

If you aren't getting any CEL's then you should be okay, but we always recommend a tune when removing cats.

What's the thoughts on stock intakes and a z1 modified intake manifold with z1 test pipes and random cbe? I know there would be power to be gained, not really worried about that but would it run dangerously lean if these few mods are installed?

Always a good idea to tune if you are removing the cats.

Currently Running AAM Short Tails, and looking at picking up the AAM midpipe and either the Z1 Intake or AAM Intake (leaning towards Z1 due to Price and not needing to cut for the install). Will I need a tune?

Anyone? Currently have Z1 Motorsports intake and AAM Shorttails.

Z1 doesn't require a tune because maf's are in same location;just underneath pipe.
A tune would more than likely benefit anyone with a Z,mod's or no mod's.

Started & was tuned with their base kit & exhaust...then upgraded the CAI https://uploads.tapatalk-cdn.com/201...efcd2f501a.jpg
I did open up the upper core a bit; so no pinching of the intake tubes.

Dyno results? Midpipe is next for me.

Didn't like how tight the silicone in the rad supports but doesn't seem to negatively impact performance.

I'm thinking i used a 1/2" drill with a 3 5/8" hole saw.....carefully cut through the fiber's in the core.
Got a handle on the drill to hold tight-would suck to slip & nick a headlight or something.

BUMP!

Putting test pipes on with my full exhaust and JWT pop chargers + MAF tubes in a couple weeks. Am I okay to run (meaning spirited driving and WOT) for the time being without a tune? Or should I put the stock airboxes back on in the meantime to do this safely?

Getting a tune this summer, but not for a few weeks after install at the very least.

You'll be fine you just may run a little lean and possibly throw a code. As long as you know your getting the tune soon don't stress it too much

As in a code for running lean or for the test pipes? I'm trying to find time to head over to Dynosty for an EcuTek tune but don't want to grenade beforehand if I get a little playful with the car.

Would a tune be beneficial for K&N drop filters, stillen HFC, light weight crank pulley. still have OEM EXHAUST but looking for a better 1. I hate the delay throttle response. THANKS :driving:

I recently installed AAM Resonated Short Tails, Stillen Gen3 CAI, and ART Pipes. I was running with the Short Tails and CAI for a few months before I installed the ART Pipes and didn't have any issues throwing codes. Now that I've installed the ART Pipes I'm throwing codes for both 02 Sensors reading too lean. My car is still fairly new and only just passed the 8,000 miles mark. I won't be able to get the car tuned until the end of the year. Is it safe for me to drive the car with the mods installed or should I re-install some of the OEM parts to be safe? Reading through this forum I've seen mixed responses. Some people say that it should be safe and others say that the A/F ratio could be thrown off really bad. Is it possible that the ART Pipes are reading the A/F mixture incorrectly due to the 02 sensor placement? I'm just trying to be safe and ensure that I don't damage my vehicle. Any help is appreciated!

if there's a local dyno shop...throw it on there & ensure you're not running lean-as this will toast your engine.
we have a local in SC w/a Dyno-jet & he put's the A/F meter at the exhaust...it should be on the rich side @wot (12.0-13.0) unless you have a vacuum leak,etc...
