[Official] "Do I need a tune with bolt-ons?" thread

JVerge5363 · 08-05-2013, 08:23 PM

Just installed Berk CBE and Motordyne ART pipes. No CEL,s. Hoping to Supercharge over the winter. Tune now or wait??? Million dollar question hmmmm.

Buy the tuner version, tune it now, and learn how to mess with it while you're waiting to supercharge it. Save yourself a lot of hassle & $$ in the long run

I just purchased z1 headers and HFC's. And I'm currently running G3's and MXP True Dual exhaust. I plan on getting the car tuned, no doubt. My question is...would it be ok to drive the car after the installation. Or should I get it installed at the tuner shop?

You'll be fine

I installed an invidia cat back, berk test pipes and a stillen gen 2 cai.

Max:
Stock: 269 rwhp, 205 ftlb@5100 rpm
Pre uprev: 304 rwhp, 230 ftlb @ 5000rpm
Post Uprev tune: 337 rwhp, 254 ftlb @ 5000rpm

More important than the max numbers is area under the curve which increased substantially.

4000 rpm:
Stock: 150rwhp, 200 ftlb
Pre uprev: 170rwhp, 220 ftlb
Post uprev tune: 200rwhp, 242ftlb

3000 rpm:
Stock: 110 rwhp, 190 ftlb
Pre uprev: 112 rwhp, 210 ftlb
Post uprev tune: 145 rwhp, 239 ftlb

As most driving in in the lower rpm the tuning made a huge difference in daily driving. During max acceleration the tuning increased total power (area under the curve) dramatically resulting in a substantial increase in acceleration as well as smoothing out all the bumps in the power delivery curve. Huge difference.

Dialed afr to between 12.7 and 13.2, dialed in more advance. In NY we can get 93 octane gas.

...

Uhhhhh.... Yeah, I'm sorry, what kind of dyno? What correction factors? Sheet?

Dsphoto · 08-08-2013, 12:10 PM

Pre uprev:

I will scan the post tune dyno in a few minutes.

Dsphoto · 08-08-2013, 12:31 PM

Why are you sorry?

the numbers speak for themselves. Tuning made a huge difference.

No doubt...

I'm not trying to rain on your parade, but your pre-tune numbers and post tune don't add up at all. Something weird is going on with that "after" dyno, as I've never seen a mustang dyno report read that high on torque for any N/A 370Z.

Also, your mod list doesn't jive with the power you're seeing, if that dyno is correct. Would have been nice to see a before and after on the same dyno, as your pre-tune dynos seem to have torque numbers in the correct range, depending on the correction factor and all. You have to understand that so many factors can effect what the chart shows, particularly the dyno's weather station readouts and what CF settings are used at that particular shop. That's why dyno testing on the same dyno in the same weather conditions is so important.

Anyway, glad you are enjoying the car!

NickBaragona · 08-19-2013, 08:06 AM

I have Gen 3 CAI, FI Exhaust and LTH and have never had a tune done. I never realized I could be harming the car?

Sh0velMan · 08-19-2013, 08:36 AM

It is more likely that you are running really rich (and down on power) but it's tough to say without data.

NickBaragona · 08-19-2013, 08:38 AM

I always realized I could get more out of my mods with a tune, just never thought I could be doing long term damage to the car?

Without some datalogging or dyno pulls to check the Air/Fuel ratio its impossible to say.. but whether you're running rich or lean neither is good for the engine

NickBaragona · 08-19-2013, 12:23 PM

Are there any symptoms to running too lean? Car seems to drive fine...

Maduro · 08-31-2013, 10:52 PM
