Uprev Tune?
 

My Z is roughly 5 years old and has over 50k miles.

I know I should've done it sooner but considering getting uprev tune. (Main reason: throttle lag)

Is it worth it on a 5 year old car?

I do plan on keeping the Z for the near future.

I say go for it! Its never too late to get a tune. If you had gotten it done at 10K miles and now have 50K, would you remove the tune? I don't think so. Therefore, whenever you get it is as good time as any in my book.

If you plan on keeping it for awhile then go for the tune. Even stock,your car will run better. Just make sure to get it tuned by quality tuner.

Absolutely! And you will feel like celebrating as if you bought a new Z. I have beer in hand. Cheers.

hmm... leaning towards getting this

It'll be worth it just to get rid of the throttle lag that's been bothering me of lately

^ This reminds me of a 55 year old lady, that was asked if she wanted a bit of plastic surgery in order to "look better" and perhaps "perform better". Her answer was "hell yea I take it".

Now if you have plans on getting the intakes, you should put that in first and then get it tuned.

^I'm cosidering Takeda over stillen due to installation difficulty lol

Did u install your intake yourself or someone else?

Some places are charging close to $300 just to install the G3s...

So I'm most likely going to tackle the install myself

Save yourself the $300! The install isn't bad, if i can do it with just barehands and a butter knife you can too! The hardest part for me was removing the bumper because it was my first time doing that on the Z, so many damn screws:shakes head:

^I've taken off my front bumper so many times I can do it with my eyes closed lol

Guess I'm going to have to contact "someone" if he can get it for me lol

Yea after that first time it's a breezy now because I had to clean and re-oil my filters. If you need a hand to install drop by my place we can knock it out in my garage.

Thanx :)

I hope it won't come to that

Lol don't be scurred i'll be gentle, with the car I mean. But ya it's easy, just follow the diy and wrap your ac lines in some rubber so it doesn't rub through the pipes.

:tup:

The UpRev will do more good than harm.....After installing my G3's my AFR mixture was really Lean....

if you plan on getting any breather mods, then i would wait for the tune. if you're not going to be adding anything, then go and get the tune.

if you get a tune now and later add intakes or whatever. you would have to get the car re-tuned.

JMO Intakes are a waste of money since we have stock CAI's. K&N Filters with Post MAF's get a better "throughout the RPM range" result. Especially after a tune. And you'll save $250

Looks like it's a definite yes

now I just need to take a sick day from work and give a visit to specialty z

thanks to everyone who chimed in!

My friend Omar is a tuner at the location here in Austin, he let me "try out" a modified throttle map for the day. There was a noticeable difference during wot for sure.

I have 4 maps on my tune which is awesome
#1 91 octaine colorado high alt tune (with mods) (320 whp)
#2 94 octaine California low altitude tune (340 whp)
#3 Valet tune 2800 rpm limited (no ferris Bueler runs in my Z)
#4 parking lot "kill tune" (no fuel tune/ anti theft tune) car won't start / run

the variable maps make the tune a no brainer to me.

Uprev tuning is definitely worth it! I had my Z dyno tuned with an UpRev rom as well as my Altima SE-R that I had a few years ago, and in both cases, saw anywhere from about 7-12 lb ft of torque gain across the ENTIRE rev band. And if you're seeing even 10 lb ft more at 7,000+ rpm (or roughly where our VQ37's are peaking in power output), you're looking at 13+ peak whp increase. IMO though, the best part of the uprev tunes is what the tuner has been able to get out of the midrange. The engines just feel so much more lively from 2-5k! All in all, I've loved the uprev tunes and feel they've been worth every penny!

Don't expect it to work magic for your throttle response, but depending on what ROM you are running currently, whatever updated ROM the dyno shop flashes onto your ECU may have updated throttle tables that could help it out.

When I had my Z dyno tuned towards the end of last year, the shop used the latest ROM and I've never had any issue with my throttle response. It's quite good.
