should I uprev?

370Z JT

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.

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

djpathfinder

Cobb does not support 2010+ 370Z.

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

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.

Mandingo

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 Intake, Header, HFC, CBE = Too Lean?.

im going to have my tune in the morning
