Do I need to get tuned?
Hello Folks. I am going to have these bolt-on's installed on my Rev -up 35th aniv Z ...do you think I can get away with out an uprev tune and wait till I get more bolt-on's or should i to get it...whats ur take?

XO2 Exhaust
Mods that's pending to be installed this month
5/16 spacer
Mrev 2
JWT oil Spacer
ART v1 PIPES
not related mods
Hotchkis Sways

I tend to collect all parts and do all the install in one shot..Now all these parts in boxes is taking up space in garage..need to install this month

I have all the bolt -ons in my garage..I just need to go to ZCG and do the job.
is there any other bolt-on I am missing? I wont do headers now. How abt any pulleys? etc..Once I got FI (vortech supercharged) I will go with JWT flywheel and clutch.

Get all your breathing boltons (exhaust/intake related), then tune it. (Minus the headers, cost/labor vs gains makes it difficult to justify doing) Pulleys are parasitic gains, free's up lost parasitic power. I could be wrong but I don't think a tune will be effected by it much if at all.

The only benefit I could even imagine you getting from a tune AFTER pulleys would be to smooth the power out a little more.

look at all the replies. haha
OP, you can use a tune on a STOCK 350z.
AND for the others... all your bolt ons that have no tune running them are NOT making you any useable power, period, period, period, end of story.
at WOT at the highest rpm possible, you may see a touch of gain because its all out at that point.. but the losses you suffer at every other point are amazing, and everyone wants to act like its the elephant in the room... its so crazy to me, it really is.
Your car with test pipes, planum spacer, intake and exhaust is not really any faster than a bone stock Z.. it just feels different as you ruin the AFR readings, curves, and expected torque of the car. ( blah blah, im not going to get real technical or wtch my words, so please dont argue them here either. im just sayin)
You need a tune to take advantage of those mods, period.
Why am i always the only one who will admit to this?
BUY A TUNE.. or continue searching until more ppl tell you its not necessary.

HR's especially with mods pick up a ton of power with a reflash. I'm not going to link any articles because I don't think they have any of our sponsors in them... But search around and see what I'm talking about.
And with the headers, leave them oem unless you want to fork out for long tubes. Those are the worst to install, but IMHO sound focking epic.
Do all your lil bolt on's and get a reflash! I'd go to a place with a dyno just to see how much you pick up. Plenty of shops here in California can do that for you (osiris tune).

its true, in many cases you will actually lose power over time without a tune. the ecu was programmed with not only minimum target values but maximum ones as well in order to keep emmisions in check and such. in other words the ecu was designed with a sort of "sweet spot" where all of the values read by it's hundreds of sensor are within a limited range of accepted values. if you throw bolt-ons on the car it often times screws with these values and confuses the car. in an effort to bring these values back to normal it will often adjust other parameters. everyone would like to think that if you add more air through an intake the car will respond with more fuel and therefore more power but this is often not the case. often times it will actual pull values rather than add them and attempt to bring the car back into "normal operating condition".
by tuning the car you redefine for the computer what it's "normal operating condition" should look like. this is the only way you will ultimately gain any appreciable power and not have a car is constantly cheating it's self out of power or running like poo.

I look through your list of mods and do a rough estimation of the money dumped into them... "been fine" isn't exactly the result I would want.
The car "comes alive" with the tune. When I had mine done on full bolt ons- it wasn't exactly like I'd installed an FI option or anything... but it trims out so many different aspects of your car designed to accommodate the soccer mums and retirees that want to have a sporty car.
Sure, you can be "just fine," or you can get some money's worth from your mods. It's tough to substantiate the money- then again for many it's tough to substantiate the substantive cost in mods. Clearly you have your head around why we spend money on mods... so the tune is a no brainer.
Uprev is a great option... but like with any other tuning option you have to make sure you take it to someone who knows the software.

I have found that it is different from ECU to ECU depending on how bad you will need a tune. HR's seem to do really well with bolt ons and no tune as the ECU's are more adaptive. here is a post from another forum we are on showing the benefits of a tune on a 2005 350z. He was running with all the common bolt ons on this vehicle for a few months and the ECU just never seemed to adapt...
Another 350z tuned today. Not a record breaking or even a F/I car. Just a 2005 350z with all the popular bolt on's. You can see how poorly the car was running and all the retarded timing and knock control being applied. Customer was complaining of some excessive oil consumption and other driveability issues since all the mods were put on and before the tune. Got the vehicle up to spec and dialed it in with an UPREV tune
