ok, so when I go to my tuner, what specs should I have him push my car for, no more than 255, a/f range 12.6-13 @ WOT?

I know there's more. I'm a newb.

 

BTW- Almost everyone has had problems with intakes/tunes with the LNF doesnt matter, trifecta, hpt, sc...

 

i just talked to superchips and they said the reason for the cobalt bogging with the intake on is because their tune is meant for the stock lnf. tune for bolt ons will be available for download shortly.

 

what are other people with trifecta tunes running A/F... mine's at 11.8 so idk where all this richness discussion is stemming from?

 

11.8 is way too rich for the LNF

 

Because different intakes have a different effects and degree of effect on the A/F ratio it is not possible for them to release a tune that fixes the issue with every intake. Some intakes cause positive fuel trims some negative fuel trims an the fix if different for each case.

X2.
I am sure Area47, 06 black, and Boostking would agree as well.

 

Anyone can answer this, I've obviously got the SC tune b/c of lack of tuners in my area (hell, we have a lack of everything in WV). I also have the dejon sri on, do you guys think I'd make more power with my stock intake?

 

More power maybe not... but drivability and keeping your A/F in check yes that it will do!

 

Oh, ok, thanks man

 

No problem... I am on the stock airbox... while I just a tune only with a K&N filter in the stock box...

Car made 307whp and 339wtq so, what I can say for the stock airbox... what it makes up for in drivability makes up for the little more spool time

 

It sucks I don't have a dyno close by to try the two and see the differences, I might put the stocker back on and see if I feel any difference...lol

 

i know this may not mean mean much to you guys coming from a 2.2 guy but vince is a beast he has taken my 2.2 and given a performance feel and he has given me no lift shift and given me a switchable tune for when i want to run nitrous and when i dont all on the fly. he is a mad scientist and has shown more care than any bring name brand i have ever dealt with. his willingness to make me happy with my tune and his dedication to his work is the best i have ever dealt with. i would recommend him to my grandma!!!

You'll feel a difference... but the you'll get used to it again after you enjoy how much easier it is to drive!

 

they said they are going to tune with aem and injen so i guess we will see. if it works, awesome. if it doesnt, back to the drawing board.

 

Okay if they fix the intake issue... are they going to fix the charge pipe issue, intercooler issues.... they all effect the airflows and change things too!

 

dont know?!!! all i know is the tuner works great on my 01 silverado with intake, headers and exhaust. thought i would give them another try on the cobalt. if it doesnt work, trifecta might be my last resort since i live 20mins from clear image.

 

Yep, and there will be some nice suprises. They see the market here...

 

**** it. I'm doing the comparo myself.

 

thats the spirit!!!!

 

I'm running the cortex on my ride with intake, charge pipes, and catback exhaust, and have to say i'm very satisfied with the tune. I'll be taking it to the track this weekend, and let you all know what the car runs. Still have to get it dynoed to see what my AFR is at as well as power outputs. There's always going to be something better, but remember it's your ride. As long as you satisfied, that's all that matters.

 

I'm gonna load that ****** Superchips tune on my **** tonight, and when I get the Trifecta I load it and see what's up.

Tired of this ****.

 

I honestly would rather you use the SC tune than Trifecta because that rich A/F is harmful to the motor over time and is more likely to cause KR because it is too rich. 11.6-11.8 compared to 12.9-12.5 for the SC tune.

 

I drove out to rockford with my girlfriend, 2 tents 4 cases of beer, a few helmets and 2 suitcases

Superchips91 octane
cruise set at 62mph , 79 degrees with all windows down, sunroof open flat road not much wind, DIC read out anywhere from 37-42mpg. I have a hard time believing trifecta could beat that.

oh, and termi wouldnt you foul plugs on trifecta pretty quick with that low of a/f

 

Why would you rip apart the SC tune and then say go with it over Trifecta?

Unless we are talking about cylinder wash - which would happen below a 10:1 a/f ratio.

How could you honestly say that it is too rich?
