First things first... I paid for all my tunes and have run GIAC stuff on previous cars and think they make fine products. I think just as highly of Shiv and his PROcede Tune. If you read my posts, I keep things professional and non emotional.

After enjoying the tune, I thought I would gather some ACTUAL QUANTITATIVE data on the GIAC Tune. So I was able to acquire some time on a Dynojet this morning... Let the graphs speak for themselves.

I was actually hoping for significant power gains over my old PROcede runs on this dyno, I will see if I can get those Dyno runs, but overall power seems about average for a car running slightly lower Peak Boost. Also at around 3.5k RPM, when going WOT there seems to be a strange boost oscillation which can be felt in the car. I do not know why this is happening, perhaps there could be an issue with the car, but it is something I did not notice with previous tunes, maybe all tunes have this and I just took notice recently.

Overall, the tune is still a great tune, just not the game changer I was expecting to see on the dyno. Now I understand why the car "felt" smoother, because as you can see, GIAC is a bit more conservative in the low RPM tq delivery/ramp.

The ACTUAL dyno is now getting me to re-evaluate my BUTT Dyno.

I still have a couple weeks in my 30 Day money back policy that GIAC has. I need to evaluate the pluses and minuses before I make my final decision.

Just a bit more data to feed everyone around here for discussion.

NOTE: I have some raw data logs if talented excel people want to make some graphs?

The GIAC is tuned for the road which explains the wiggled in the curve and perhaps the lack of HP.

Did you test out the Procede in this same dyno and what where the results?

Yes...a bit over a year ago with the older PROcede, and it did about +5HP on the same dyno so the "PEAK HP RESULTS" were similar, but TQ was higher at around 20FT/lbs or so. I will need to dig around to get those, also the oscillation can be felt on the road...

I am only going to assume the newer maps are even stronger...

What version was the Procede? And what mods did you have with the Procede vs the GIAC?

The first version of the RevI, before the PnP harness was available. V1.47?

NO engine mods other than the tune.

Glad to see another dyno!

317whp/335wtq sounds "OK" for a car with your level of mods running 13.5 psi of boost on a stage 1 tune(as GIAC claims).

I would expect a bit more power, especially since your v1 procede made more on that same dyno.

I hope they figure out that boost oscillation issue... especially if you are feeling it ON THE ROAD.

[bigpuna]

Power seems ok but with the boost oscillation issue, average power and higher price you would be better off with the ESS stage 2 or 3 flash. What mods do you have on the car ?

[Driver72]

This is what many of the other tuners have been saying all along.
Boost is boost.
You are not going to see one tune that runs 13.5 psi peak dynoing at 340 rwhp and another tune that runs 13.5 psi peak dynoing at 315 rwhp.

There's only so much you can do with air, fuel and timing. The vast majority of the power comes from boost.

317 rwhp on a tune only car on 91 Octane seems about right (maybe a bit low as some of the others seem to run ~325 rwhp at 13.5 psi peak)

No doubt your torque numbers are 15-20 rwtq low and seem to drop off faster than the piggyback tunes too.

Has any one Dynoed a Dinan stage 1 or 2 software tune?

I did. I dynoed st.1 dinan with aa catback and got 310 whp and 333tq. 11.5 psi peak. Very similar to his results. 91 octane.

[stillclaimndp]

I was there when it was dyno'd the first time, it was the very first map introduced for V3 and it made about 323-325hp at the wheels... It was a similar day in terms of whether, this time last year, you can find my posts on this forum. The current V3 Rev2 should make +12-15hp over that version as it has evolved since.. This dyno does read a hair lower than most dynojets but is also the same dyno used by Vishnu and you have seen what they are able to put down on it but this dynorun was performed by the owner of the dyno.

Thx for sharing

[Ridge335i]

Lolz...and now the true power numbers come out. JB3 or PROcede ftw.....

Yes, with a Borla cat-back and aFe DCI only.
Dyno'd @ a best 326rwhp/328ftlbtq on a DynoJet.
78% humidity & 93 degree heat index.
Dinan Stage II
max boost recorded @ 13.9psi

Since then ....... no.
Curious though as I now have the AR Design downpipes, Helix FMIC installed.

But smoothness (no lag) = flash FTW

Piggy's have had years to develop on the n54, the flash game is just getting started.

...... ever since the Dinan flash I have had ZERO lag and continue to enjoy it.

There is no less lag with the flashes. Just less torque.

Actually, maybe it's the fact that I've managed to retain the original pre 29.2 progman and the original Dinan flash. ..... but, there is definitely no lag here whereas there is noticeable lag with each of the piggyback tuned cars I've ridden/driven in. Not much but, still noticeable.

I think it has to do with the progman version on the car. Mine is dated 01.01.07 built and never upgraded since then. I have ZERO lag with JB3 maps lagfix or not.

[OpenFlash]

All turbo engines have turbo lag. That is just a fact of life. If you think you have ZERO turbo lag, you probably don't know what you are looking for. But if you managed to reduce your turbo lag by 50%, you'd know it in a sec.
