Is a tune really worth the money?
 

I have heard you really only get about 6-11 horse power from a tune. I have my stillen gen 3 long tube intake and my fast intentions CBE with test pipes. The next step would be a tune but is $500 really worth it for just a difference in drivability?

Its not all about the HP increase. These cars with all those mods tend to run Lean. If you want to get the most out of the mods and keep the car running safe get a tune.

You can get quite a few hp from a "tune", just need to ask yourself why the Nissan engine calibrators didn't "tune" them. I'll let you ponder that.

Umm... they kinda DID.

Very conservatively.

@OP, the tune is like night and day. The actual hp/tq numbers aren't that different most of the time, but the throttle response is way better, the car feels much smoother, plus you get the maps so nobody can steal your car at night and take it for a joyride. You can also get way better mileage, I've heard stories of 30mpg and up, if you're into that kind of thing. :tiphat:

Most likely you're not going to see a massive increase In fuel economy, from what I've seen the VHR motor makes better power when it's a little richer, and you'll most likely have your foot in it a lot more :D

The improvement in drivability is amazing tho, really night and day

Because they need one cookie cutter tune to fit thousands of cars that will be all driven in vastly different conditions in different regions of the world with different levels of maintenance and mods..

Every engine is different and will not perform identically as the next, you can always benefit from a custom tune

u will pick up a ton of throttle response and all the low end tq/hp u lost by adding all that air with the breather mds.

Where do I get a tune performed? Anything near the Charlotte area?

This really depends on what you are tuning for. Do you want more performance or better fuel economy? Performance helps fuel econ but I doubt a performance tune will get you over 30mpg. You can tune down performance and tune up efficiency and you definately will see high fuel econ.

IMO it is worth it. My Z really woke up after the tune.

Make note this cookie cutter tuned to handle both high desert heat to low Canadian snow to Seattle's endless rain.

Whenever you change anything to aftermarket parts, you're deviating from the original manufacture specs where the manufacturer set it to handle wide variety of environments.

If you know you're not cross country from Canada to Mexico and just leaving your car within your environment, a tune will definitely increase both power and gas mileage because you're narrowing the engine's expectancy in dealing with environmental temperature and humidity ranges to best suites your local environment.

A tune is definitely worth every penny. My mods are Stillen Gen 3's, F.I. HFC and F.I. 18" res. CBE. Before Tune - 301.3hp 248.27ft.lb. After Tune - 319.02/265.84

Do we buy the hardware and preform the tune ourselves? Or did most of you opt to send it in for tuning?..

Would you consider this for a daily driver? I'm thinking of the F.I. HFC and F.I. 18" more or less to get a better note.:tiphat:

The best mod I've done hands down. It became a different animal and I've driven many untuned 370s since then and felt so disappointed. For $500 I got 31whp, 5 maps and ride along tune to adjust a/f to improve mpg's while cruising. Uprev + VDC off = a whole lot of fun and a big stupid grin on my face :tup:

You CAN do it yourself, but unless you really know what you're doing you'll want some professional help.. There are 2 ways to do it:

Go to a shop and have them dyno tune you, or buy the tuning software separate and have uprev adjust your tune with datalogs or your driving over email (etunes)

EDIT: Or buy the tuner version and do it yourself :p

Is it worth the money if I just have a cutback exhaust and drop in air filters and a red gt-r button ( :D )

I think its worth the money, but thats just me :p You could buy standard with the 3 etunes, get one now, then in the future when you get more mods get another etune update, etc... and you'll have a tuned car pretty much the whole time. Or you could get the tuner version and just tweak the A/F yourself after each new mod... once you have a base its not too difficult.

If you're going to get on a dyno however I would wait till you're done with bolt-on's.

:iagree: gonna get my tune done soon. :tup:

some mild mods here too cat-back, filters+tubes. I'm getting an e-tune through R/T Tuning Speed Shop - $500. Added benefit of having the cable is I can run diagnostics, clear codes, reflash on my own, and the cable has good resale value. If you have a 7AT a Tuner can adjust your torque management tables + line pressure increased, fan speed (cooler oil temps), throttle response, AFR's, adjust to your specific type of gasoline.

If we had OpenECU availible we could save a bit of money there and have all the benefits except for maybe switching maps.

You'll love your car more after the tune

Definitely! I daily drive my Z.

Thats the same price as direct from uprev... do you get 3 etunes?

My car is scheduled to be at rt tuning to 30th I can't wait only a couple more days! From my research a tune is really worth it and it seems the Vince from rt is one of the best in the country with our cars

Where did u get it done?? 31whp??

ride along tune.... so they had no dyno?... lol

CIN Motorsports in Charlotte, NC and yes 31whp from the tune alone.

It was on the dyno for a few hours then we rode around with the laptop and made changes on the fly while cruising on light throttle.

I'm in Charlotte right now but didn't drive my Z, blows

Agree with most of what everyone said, Tune is worth it 100%, Will change the way the car reacts, safer AF's( If you have I,E). I made 298 on a LOW dyno( Mustang) with a 7 SPD AWD, You will see a HUGE gain in the mid range, Thats where all my gains where, I made 296WHP before my tune but picked up my 30 or so WHP and 20 or WTRQ in the mid range. Do it you will not be disappointed 1 bit,
