end of story.
in your other thread you said its not the stock conti's that right there could make it not spin.. so not end of story lol factor that in.

mildly tuned tc with good tires wont spin second, its right on the verge of losing traction but may not.

It would be closer to 6 sec. I just timed the video posted on this thread of a stock car on a pull in 3rd from 60-100 and it took 7 sec. That would translate to around 6sec to 90..just what I would expect, btw. That's why I have good reason to believe my car ain't stock. I'll get around to pulling the full run soon.

Standard Trifecta tune running Vince's prefered AFR still broke mine loose in 2nd on the Conti's but anything stickier wouldn't have. Ronns boost levels leads me to believe it's a mild tune like TF or Superchips.

HPTuners will read entire the Trifecta tune but I could never open the TF file after I saved it, I have no experience with the Superchips.

At any rate, you can squeeze more out of it when/if you are ready.

I'm running an HP Tuners tune on top of the GMPP base tune and sensors.
I hit 25, hold 24 to ~4500 and taper to 16 psi @ 7k. Catless DP & a free flowing intake raises the air flow #'s but the freer exhaust lowers boost pressure. Still makes enough power to break second loose at 4k through 7k. It will break loose in 3rd in cooler temps just nailing the throttle since upgrading the clutch. It used to slip.

If you want more than that, you need to run a 24 psi Trifecta tune but the turbo becomes greatly overspooled at 24 psi above 4k or so. The GMPP tune keeps a very lean midrange AFR (read Lambda in the LNF) and conservative timing same as the stock tune and tapers the boost at higher rpms to save the turbo.

A few are running HP Tuners over a custom tweakable Trifecta tune so they still have some control. HP Tuners hasn't unlocked all the tables we need for all the toys like 1:1 throttle, wastegate control & fuel pressure.

From what you have posted today, you are at or above the GMPP tune levels.

Just my guess.. but I'd bet a superchips or mild trifecta.. I'd put money on superchips tho =p Curious what it will be when you find out tho
Btw, what kinda tires are on it? Just curious cuz I'm gonna need new ones soon and being tuned, it does spin all the way thru 2nd unless the asphalt is hot n sticky, or at a prepped track.

Have you tried the cruise control on and off thing that trifecta does with their selectable tunes ... or the traction control modes? Does it redline at 6300? What is the launch control RPM? A superchips tune can have a stock redline or 6500 . It has a 4000 rpm launch control limit thou.

What's with the battery being replaced here?

I sent Vince the VIN and approx time frame the owner had the car:

I don’t see any record of having tuned that car.

Trifecta Performance, Inc.


Found this thread on another forum...this leads me to believe I have a tune that has muted the learn down feature which would vary the boost depending on mainly temps. I have found I boost the same ...hot or cold weather and at 20-23 levels.
Can't post link here:

Quotes:

Normal stock boost level truly depends on the altitude, here in WV I'd hit around 16-17 in warmer weather, now I only hit around 14psi.

during the hot days i will booste about 23-24 and the colder days it only 22-24, but my car runs alot better and feels to pull better when its cold
This one *reminds* the previous poster that his boost is modified

Hey skoal, with our tunes our learn down feature has been removed. I mean, we obviously still see a slight fluctuation in boost based on weather but not as bad as when we were stock.

All this points to my car being in the latter category.

Ive been following this thread along with the "new ss ex-racers's take" thread.

My 09 does 20psi in 2nd, and 18psi in 3rd until it hits 4400 rpm then it spikes to 20psi and then it's 20-22psi in 4th and 5th, so I think it could just be normal.

I mean it fluctuates between 18 and 21 depending on the day, so i will be surprised if ronn's car has been tuned.

Also, if it were tuned, would the dealer have been able to spot it during their 948 point inspection?

Compelling saga though, keep us posted...

I shouldn't speculate further since I don't know much of anything about tuning, but it does look odd. But the numbers don't seem strange.

They are pretty much what i get give or take, and depending on the temp/humidity/dew point.

I would say get rid of the tune. Go with GMS1 or one of the folks on here that is good with HPT. My only beef with going HPT is that, as far as I know, none of the tuners beat and monitor their cars on a road course. Say what you want about a tune being a tune, but all sorts of **** breaks on tracks that you do not get from running around on the street and drag strips.

Me? I'll take the John Heinrichy likes.

Area 47 beats and monitors his.

John Powell beats his and sends the logs to Area.

Theres something you can do to see if your tuned
Run 25mph in 2nd gear, floor it and see if you are losing traction

untuned it will be quick but not really lose traction, once tuned its a wheelspin for sure, even on 20psi tune.

Like in a video i made when i got my tune:

stock vs trifecta 22psi
http://www.youtube.com/user/huckerna...35/9kwBWGptAQo

If it can give you an idea...

OK I finally have an answer using the video!
http://www.youtube.com/user/huckerna...35/9kwBWGptAQo

At first, I just timed the whole run...and tried to adjust to my results...difficult The answer as to how my car performs to stock and trifecta was right in front of me all the time! Time just the range on the video that I tested...62-94 (100KMH-151KMH)!!!
Ok here it is:
The STOCK run in that range was ave 6.1 sec..my car is 5.2 sec
The Trifecta run in that range was 4.7 sec ave...my car again 5.2
I know the views have some parallax and the video speed *may* be a slight factor, but I used other video speeds and they were almost the same. I took around 10 sessions for each and got the average. So, it looks like my car is between stock and Trifecta..being closer to Trifecta, It's DEFINITELY not stock.

How are you timing this with your stopwatch?

LNF or LSJ? I don't recall ever having heard of an Area 47. Maybe he predates when I started to read this board.

I have the video playing at slight magnification with a stop watch in my hand. As soon as the needle hits 100KM (62MPH) I start the watch and when I see 150KM (94 MPH) I stop it.
Did that 10 times and took ave. I checked the timer running at the bottom and its very close to my stop watch. It isn't *exact* but it's pretty damn good for comparing my *in car* results. The difference between stock in this video and my car is well beyond error measurement.
I'm going to try to do the FULL run (as in the video) soon to compare. I have those #s taken off the video as well.

notice its 90kmh to 155kmh, the speedometer make it look like 150, but im almost at redline when i left off.

90-155kmh = 56-96 mph
