Out of curiosity.. Were you tuned during the summer? Did Vince know the car would be driven in an area where the temperatures could be as low a -40 or -50?

 

you are right on that. We use it for his SOFTWARE, not his tuning. Just because he is an excellent hacker does not make him a good tuner. As far as tuning, not the best. If you want a tune that does not get the full potential of your mods then power to ya i guess. Honestly i wouldn't spend the money on a turbo upgrade if thats the case.

 

yeah and a car Vince tuned put down over 330whp and over 400 ft-lbs last week end with bolt-ons........damn, that sucks

 

haha bench racing at its best. dyno numbers dont mean squat to me

 

i vote spark plugs, mine did that to when i had plugs my car didnt like

 

...but you just said we wouldn't get the full potential out of mods... there are very few HPtuned cars putting down that kind of power with bolt-ons..... just sayin'

I agree with you that its not all about dyno numbers... however with my Trifecta I turned a 2.0 60', ran the 1/8th mile at 8.3 seconds and trapped almost 89mph as well, so guess what, i'm making use of that power as well....looking at the stock turbo times on the top 10 list.......about on par with the Godly HPtuned cars


my actual slip was:

60': 2.007
660'(1/8th): 8.324 seconds
Mph: 88.760

i'll be hitting the dyno at our dyno day in May


and our big ugly slip from that sorry ass track:



and that track just recently closed

 

That's about 5mph more than my bone stock SS S/C.

 

and in 660'.......that is several car lengths... lol

in 1320ft.......that'd be about 12mph faster than your stock s/c considering the final 660' is a turbo car's strong point, in which case at that point you use bus lengths as the measuring device... not car lengths



if a car is 5mph faster than you in the 1/8th....you pretty much just got curb stomped, because I will bet good money you're stock S/C isn't breaking the 8s, in fact I bet its running 9.3s or worse... and a second through the 1/8th mile? 6-7 car lengths in 660'... that is one of them sit the f*ck down races

 

Not everyone is after the most aggressive tune for power.
In 5 years from now when your car is tore up, and you've rebuilt the engine a couple of times and I'm still running my BNR turbo semi-aggressively tuned car around, you might get it. (different strokes for different folks).
Some of us would rather take a slight hit in power so we don't break stuff all the time. With big power & aggressive tunes, its not a matter of if, but when something breaks. Which is fine, pay to play if thats what your after.

I have a totally different vehicle to thrash on at the drag strip then my HHR SS DD. SO I do know a thing or two about modding and I'm not talking bolt on's lol.
Pretty bad ass to and something you would never expect. (Bama08 has seen it while I was still completeing it)

To date, I have run 26 psi for over a year on a Trifecta tune on stock K04 (which was perfect when I exchanged it at BNR) and running 26 psi now on the BNR turbo.
I have NEVER, let me say that again, NEVER been to the dealer for anything other then getting GMS1 installed back when I bought my car.

I for one do not believe in any of the stories that Trifecta is a bad tune, it may not be the strongest, but it has been a safe tune for me, even at 26 psi.

Now I'm done arguing and cluttering this dudes thread up.

 

To everybodys posts, my A/F is is between 14.5 to 15, also measuring lambda of ~1, I'll have to check to see what I'm running for everything else tomorrow, I cant see it being an o2 issue unless theyre known to fail in situ like that without being handled. Like I mentioned plugs were just replaced and were running strong for over 5000kms with no issues and were OEM replacement plugs. I'll definately look into this if Vince suspects something is wrong, but from what he said the misfires being scanned were likely not 'real' misfires and some Knock is common on the parameters of his flash while not in competition mode. Thanks for the info so far guys!!

 

People who pay others to tune their car, arguing with people who actually tune. PRICELESS. lol

 

my argument has never been which is "better"... all i've said is as of right now, the Trifecta cars are pretty much on par with the HPtuned cars in e.t.s with the same amount of mods...

someone said earlier dyno numbers don't mean ****... and I couldn't agree more, but why is it every Joe on here will calls himself a tuner once he gets the Hptuner software yet if you go over and check the drag results page, hardly anyone is showing us their work doing work... I know not everyone is a drag racer but if you want to benchmark, its the most accepted means in benchmarking where you were stock and where you got to with a tune/mods... no one cares what you dyno, no one cares how hard you pull on a damn highway... show us how you can get it off the line, what you trap, and what your e.t. was, anything else is just blowing smoke out your ass

oh and i'm sorry but buying Hptuners and having BYT, Blueberry, Area47, or whoever tune your car.......yeah, that is no different than buying a EZ flash cable in terms of "street cred" which is the laughable card you seem to be wanting to play

I don't give a f*ck who tuned my car, if it pulls hard, that is all I give a **** about...

 

Hpt ftw

 

This is ricer bench racing math at best.

 

PS, it's a good second and nearly 10mph more than a stock SC car.

 

Please enlighten as to what the difference is between running the car on the street to log the data, and rolling the car on drums to get data? Either way, the tuning is done exactly the same to the car. The difference is where you get the data for the re-tunes: street driving or drum rolling. People calling Trifecta tunes, where the owner has sent data back and forth to Vince, are completely ignorant as to how the Trifecta tune works.

 

So who actually tunes in "real time"? What tuner do you know that sits with a laptop in your car, on the dyno, can see the data in real time and make corrections on the fly? Tuning is done the same no matter what. You start with a base, see how it does, make intelligent changes to it, and see the results. Then you lather rinse and repeat.

 

ProjectScarab was banned

Just thought I would inform everyone of the wonderful news

/off topic

 

To get back on topic, as has been said start of with the simplest fixes and work your way forward from there. Bad tank of gas, spark plugs, O2 Sensor, Coil(s)... If all that fails flash back to stock (if you have the dealer kit) and take it to the dealership let them diagnose the problem for you.

If I understand what you wrote correctly you have a Trifecta Tune but your not using it for winter right? Your just driving around on the stock tune correct? All the more reasons for these idiots jumping in here saying that a shitty Trifecta tune is causing all of your problems to shut up.

This is such an ignorant statement it's amazing, what the hell are you even talking about? First of all the guy isn't even driving around in tuned mode but in stock mode, second of all since when is a properly data logged and tweaked Trifecta tune a canned tune?

And like has been said stop with this Trifecta vs. HP pissing contest. A mild Trifecta Tune (done by Vince) that has been properly logged & tweaked is hands down better then having some "local" guy with a lap top "dyno tune" your car. There are probably only 3 tuners on this site I would let anywhere near my car and Vince is definetly one of them.

 

If you guys don't like what I have to say, just ignore it. I'm ignorant, I get it now. Thanks.

Its my opinion, you guys are entitled to yours. I'm not here to argue. That is all.

 

Okay, I have no idea who you are but.... "He's making a tune, you're trying it...if you have a problem, he makes something else and you try it. You see the pattern?" IS THE TUNING PROCESS WITH ANYONE/ANYTHING. You can't expect any tune to be dead on right when you load it into a car. Have you ever tuned a car, or is all your time spent on these forums making asinine responses?

Proper tuning REQUIRES testing and adjustments, that is how you get the most out of any tune.

 

You have moving area and changes in load on a street tune, and in some places changes in elevation. The Dyno simulates load, its not always dead on. Also on a street tune you can adjust tq management to see what helps you get the best traction. You cannot do this on a dyno.

 

Are some of you seriously trying to say that a street tune is better than a dyno tune??

Are you guys stupid? Go to any professional engine building shop and tell them that tuning is better if done on the street and no the dyno......prepare to be laughed at.

 

Well I guess that settles it, dyno tuning is better

A quick search online shows many other sites have had this same argument more then once, none of which have I seen a consensus on.

 

How many shops are going to take a customers car out on the road and do multiple 100+mph runs to dial in the car. Hell of a lot easier/safer to simulate it on the dyno. It would take some serious skill to total someones car on the dyno
