Quick question
 

I have the Fast Intentions exhaust and just ordered the Stillen Gen 3 intakes. When I put the intakes on, will it be absolutely necessary to get a tune or do you think it will be fine. I will be getting a tune in the future, but just don't have the means to right now and don't want to be too leaned out.

Nobody has the answer to this?

you should be fine, but get a tune sooner then later. i have G3 intakes and a CNT CBE, no tune, yet.

No tune nesseceary unless your anal about extracting every bit of power. Honestly if your gonna continue modding with N/A mods. Get all the bolt ons them pay for a tune. Rather than mod, tune, mod, tune... It gets costly if you do it like that.

:iagree:

I second... not that much power that comes from a tune... but it might get you a little better mileage overall ... so that will save you a little money in the long run... but do you drive like that? lol

:facepalm:

Generally you're able to get away with the Gen 3 intakes, cat-back exhaust and EITHER HFC/TP or headers. When you run headers AND HFCs or Test Pipes, you'll be in a lean situation and tuning is mandatory.

That being said, most will go UpRev if they have Gen 3's, cat-back and HFCs, which will dial in the A/F ratio, and pick up 8-10whp..

:iagree:

id say yeah get a tune.

If you dont want to dyno tune get a base map tune for your mods

I had John @ Z1 do a base map tune for my 2 mods and it made the car run quite alot smoother. Its actaully quite disappointing to think how long I drove around with it before.

When I get some other mods added on, i'll be taking the car back to John and he will Dyno tune it. The same uprev license will be used. might cost a bit more to get it done this way (2 stages) vs just a full dyno tune, but i think its well worth it.

Will there be a fix for the MAF sensor like AEM has for their intakes?

Please explain how N/A mods is detrimental to the car without a tune. Bolts-ons on the car won't mess with the car so much where your so lean that its dangerous.

Obviously the car will run better with tune and gain power but your talking about $600 dollars a tune for just N/A mods. If you were F/I, you have to have a tune to run the car.

Most people do not go with the headers as most already know that they don't do much. Only proven header is the FI LTH. Other than that most have ran the car with I/HFC or TP/ CBE without issues.

But would you pay $600 every time you added a bolt on? All I suggested is that he get all that then tune. Not everyone has $$$$ disposable to shell out for a tune after a $300-500 mod was added.

You can do enough with the airflow on a full set of bolt-on's to bring the car out of the range where it can adapt and run lean. The Z runs a very adaptive ECU, but it can only do much. We've seen the trigger being the combination of the headers and removing the factory cats.

Yes, agree with your position of get the mods you're going to do, then tune for maximum $$ savings. But remember part of what you're paying for in the tune is the license itself, which UpRev runs $300. Anything beyond that, and you're just paying for dyno and tuning time, so it gets less expensive.

If you're really wanting to geek out and go to town, you can also get the Tuner version of UpRev, and you can tweak most things yourself. More expensive route? Absolutely.. but a lot of enthusiasts enjoy learning the details of tuning, and UpRev's tuner version will do just that. It's not the full package that a tuning shop will get, but you have enough leeway to hang yourself if you're not careful.

That's what a tune is for. Those MAF signal modifiers are a kludge and unnecessary if you just get a tune anyways.

Sorry to change the subject but I am really new at this...
but what is tuning?
Is it like adjusting the settings or something?
lol... thanks for helping out guys =)

Yeah, They tune your NOS timer so you'll run 9's.

Otherwise you'll be unloading in third.

"As long as we can get overnight parts from Japan"

Generally its means repgrogramming(flashing) the factory ECU to change alter the stock settings related to Air/Fuel Ratio, Ignition Timing, electronic throttle control, speed and rev limiters, etc. UpRev is probably the most popular option for the 370z. You could also tune by replacing the factory ECU with a aftermarket standalone engine management and tuning that, but that is typically more money and hassle than it's worth.

if your shop tells you its 600$ everytime you tune they are ripping you off.

you pay a good amount the first time because you pay for the license for the tune and then they have to start from scratch to dyno tune your car

after that, if you ever retune, it shouldnt take them that long as they need to tweak the tune vs start from scratch. Now that is unless you go from an NA build to an FI build, then tuning might take longer but still shouldnt be 600-700$ cus you already purchased the license the first time. unless you had a complete overhaul of the engine

without a tune.... you'll be granny shifting; not double clutching like you should..

So just to recap. With FI Exhaust, FI HFC, and Stillen Gen 3 intakes I will be good until I get a tune?

I would get the tune. like i said, it makes a big diff in how the car drives even if you dont have a ton of mods.

^^+1

I got tuned last weekend and it made a good difference. Definitely worth the money.

Have a look at my experience: http://www.the370z.com/canada/40765-...dyno-tune.html

I would recommend one. My car is a completely different beast.

but the answer is: you dont HAVE to. but it would be worth it

uhh... yes.

lol it wasnt a question :P

:facepalm:

confuscious says "wtf?"

Exactly.. of course it's recommended.. but sometimes getting the $$ freed up to do everything you want takes time, and as everyone has said, you should wait for tuning until you've completed at least phases of bolt-ons, so you're not spending extra to re-tune at every step..

b-i-n-g-o

I think my car is finally adjusted for the intakes. Actually makes my exhaust quieter on start up. But I love the sound at WOT and the power I gained. I can definitely tell a difference.
