should I uprev?
 

I'm wondering if its worth it to get an uprev tune for my car, it only has stillen g3 intakes and a tanabe exhaust. I'm not planning to add HFCS or anything as it would be a hassle for me. Also, does stillen do uprev tunes? I live like 5 minutes away from them.

Stillen does do uprev. Probably not worth it if it's just those two mods.

not true

a tune will get it leaned back out

all it takes to run rich is after market intakes and cbe

i would do it

yeah i can't do HFC's or anything. From where I reside, cops are bored enough to just pull you over for the slightest thing.

Go uprev - i think 6-8hp with cba/intake :)

As kdo2milger says, it goes Rich..

:iagree: I believe it will void your warranty too!

Huh! I thought mods leaned the car out, and thats why everyone wanted a tune? If its running to rich than there is no danger in that. Running to lean is a different story.

NO IT WILL NOT,,AND your car will run better alot better,,OP DO IT

I DID AND IM MORE THAN HAPPY

how much does it cost at stillen?

Diff do the Up-Rev tune through Stillen. Alot of ppl dont understand that you DO need to tune your car when you add parts to your ride. Try telling a guy with a subaru that adds a aftermarket intake and not tune his car. Car will run like S#*t, simple as that..
It will be one of your best investment you make on your car. Please note I donot work for Stillen- I just know there good at wt they do..

Definitely do it if you are done with your breather mods. You're likely running rich right now. You will feel a noticeable difference in the torque curve (better acceleration in the low to mid range), and it will lean things out. I did it with my FX45 with just an intake and exhaust, and just did it with my 370Z last week with intake, HFC and CBE. A tune is money well spent to optimize your setup. I would definitely recommend a tune to anyone who's finished doing breathing mods.

Yes, Stillen definitely does tunes with Uprev. They've done a lot of tunes on various makes and has the experience to do a proper job.

Call me crazy but I live 15 mins away from stillen but opted to go to specialty z which is 90 mins away. Lol

Last time I called they (stillen) wanted $275 for the license and $125/hr for tuning.

If you can get a dyno tune done for $600-700, it is reasonable. So even if it takes 3 hours for Stillen to do, at the rates you posted, it will cost $650...pretty reasonable, and I don't think it'll take them more than 2 or 2.5 hours, really.

Yea their up rev tuning pricing is on par with Specialty Z. However, they charge a lot more for base line pulls than Specialty Z.

So in the end, if the total cost is the same/similar, then pricing is not an issue, no?

right. Uprev pricing is the same.

I just saved some money getting base line dyno pulls from Specialty Z. So that's why I'll take it to Specialty Z for my Uprev to keep the dyno the same.

You bring up a good point. For repeat dynos, going back to the same place is a good idea because you're getting pulls done by the same machine, so that becomes a constant. Given that there will be other variables that still come into play, such as ambient temp, humidity, altitude (if you go to another city/state), etc.

looks like ill be getting one soon :D thanks guys

im pretty sure its worth it even if you have no mods for the other things it does for your car...

i have a valet map where it can not rev over 3500, a launch control map which i never use but its there (set at 4700 for track days with radials, dont use it though) , a dead map where the car wont start ( great for parking at suspect places ) or in stadium lots where you keep your key...

also throttle response is improved and im pretty sure there is power to be made even if your car is stock in the mid range area...

+1 to get the tune

Do it, All I have is Stillen gen 3's and a CBE got 298WHP out of it, Picked up 10+12 WHP in the middle of the power band and made the car a lot funner to drive. I paid $500 flat for everything. Kaizen FTW.

I'm thinking about getting it as well ... Looking to do exhaust/intake so it may be worthwhile . How similar is this to the Cobb ap

Cobb does not support 2010+ 370Z.

yes i know this, i was just talking in terms of the tuner is it similar :)

100% TRUE,,,,,,,i want the launch control map at 3000rpm wonder how much my tuner would charge to add that LOL

Thinking about getting Uprev also.
What do tuners use to measure the A/F ratio? Its not just the stock sensors right? Sorry if thats a dumb question :hello:

Depends on the tuner. The car has both narrowbands (to verify the cat works), and widebands (for fuel control) on each bank. So it is possible to tune based on the stock widebands. Often the dyno has it's own O2 that can be stuck into the tailpipe, or into a spare bung in the exhaust.
The narrowband can also be temporarily removed and the dyno's wideband put in it's place.

Makes sense. Thanks!

I still need to do my write up of the Uprev I got recently and I'd have to say I love mine.

With my mods I net'd around 290-300rwhp and I think 250rwtq. :)

Once you add breather mods (I.E. CBE, Intake, longtube headers or, HFC or headers) it would be beneficial to tune the vehicle. These mods will lean out the car. If you do all four mods it can be detrimental to the engine if you do not tune it. With the mods the OP stated it is not a must but definitely recommended for both AF reasons in addition to getting maximum benefit from money already spent.

There is another thread that goes into depth on breather mods and AF ratios posted here http://www.the370z.com/intake-exhaus...-too-lean.html.

im going to have my tune in the morning :D

Who's doing it ?

Getting it done by stillen. My baseline is at 291.4 with g3 intakes and a tanabe exhaust. Waitin for the car to cool down before we start again.

Well. I'm losing some power. I seem to be stuck at 290 lol.

Got mine done yesterday by Specialty Z up here in the valley. Well worth it. After 5 passes I ended up with 318whp and 258tq. Overall it feels much better. I do have the HKS cbe, F.I cats, Injen cai, and stillen pulley. So, yes, uprev.

^I'm going there next month.

What were your gains after tune.

the first pull seemed too high, it ended up being 284 as a baseline. ended up with 297whp, and around 248 torque or so. tanabe exhaust / stillen g3 intakes

Pretty good. Member theflyest got 286 pre tune, 294 after tune with I/HFC/E at Stillen.

Sounds about right to me.. Same numbers as I have Same mods. Intake,Exhaust. Good numbers man. :)
