YouTube - trifecta22psi_vs_GMS1

that should show u the difference in your tune and the tunes everyone else has. it may have put u at 23 psi, but like stated before it doesnt put down near as much power as a trifecta or hp tune.

 

i believe that the tc wheels are like 22lbs each or something like that

ninja edit: yea...what rissa said

 

lololol

 

My internet connection out here isn't good enough to watch youtube videos, but if you would have read the earlier posts I mentioned an interest in trifecta tune. My question which no one could reallys answer is....if I get a trifecta tune can they change it back to gms1 if need be. Would GM be able to detect this? Another question that no one really answered. I recently purchased a hahn intake. Will I see results out of that while still using gms1?

 

yeah you will have teh fastest cobalt eva!!!!!

 

Trifecta has what they call a "stealth" tune and a switchable tune, where you get 2 maps that you can switch back and forth between. In your case, you could have GMS1 for one, and when you hit your traction control, it would switch over to the Trifecta tune at 22-24ps or whatever you wanted. If the dealer tried hard enough, they could find a tune no matter how hard you've hidden it. It just depends on the dealer, try going to one that doesn't care about mods. As far as your intake with GMS1, if you see any gains with the intake it will be minimal.

 

I'm pretty sure, that you can bounce back and forth between gms1 and trifecta. The whole select-a-tune or whatever. If GM searches hard enough, I'm sure they can find the tune. The gms1 isn't written for a Hahn intake. I believe that it does do away with the whole learn down feature though. SOmeone correct me if I'm wrong...

ninja edit again: damn it Rissa...

 

Before I bought the intake I did a lot of reading on it where people were claiming 15hp regardless of tune status, so that is not good news to me.

 

Well your trying to learn so I'll help.

Trifecta has a tune that is switchable with either your cruise control or traction control button. Also i think someone has a keyed switch to activate it. In this case you can run gms1 on one file and trifecta on the other file. This means you can take your car to the dealership on the gms1 tune and there are no cases of it being discovered yet. as for the intake you have to get a proper a/m tune for the intake to be helpful, the gm tune will not be tuned for it and will skew your fuel trims. iirc the hahn intake skews them up to 15%?

cliff notes: yes and no

 

yea rissa and iboost answered it, trifecta hides the tune with either ur cruise control button or traction/competitive mode button. u can run gms1 all the time then hit the button and change over to trifecta. if ur worried about warranty just ask ur dealer if it would mess with it, and if it does leave it gms1. most of the time dealers dont care/wont look for it.

for ur intake, you wont see much from it, I answered this in my original post. you get a sweet sound from it but thats all. u see good gains from a catless dp, but will have a check engine light on unless u have trifecta remove it with ur tune.

 

hehe :P

 

OP the rims suck the ride looks high, and you are a dick.

 

There are better mods to purchase with the money that you spent on that intake. I have the Hahn intake, but it was one of the last things I've bought...

Theres more restrictive things on this car

 

I respond to what I'm given. Give me a mob of angry SS bloggers and I'll give you the fuel you need for your mob fire. Give me intelligent info and I'll give you intelligent responses.

 

Guess I will just have to try the intake both ways and see for myself, because don't know if I really want to do the aftermarket tune just yet.

 

It's not like this is the first time anyone has ever commented on my car, so I already know my rims look good. They are not most people's favorites, but they do look good. I have been saying my car looks too high for half a year now, so I see exactly where you are coming from on that. If you talk to me the way you choose to then yes I will be a dick to you because you don't deserve to have a computer to type on.

 

You will see a gain at first, but this car has what's known as a learn down feature, it does whatever it can to maintain the constant 260/260 factory power rating. Upon first installing the intake, you might see that magical 15hp gain, but the car will realize what's happening, and bring it back down to stock power levels. This is when an aftermarket tune comes into play, it removes the learn down feature.

Well my car is already at around 280/320 with the gms1. Same situation?

 

I'm not 100% sure if the GMS1 removes learn down or not.

 

Well it took quite a while but I found a couple people worth listening to. Thanks.

 

It either removes it, or raises it. I've never really looked into it. I'm sure there's some people in here with GMS1 that can share.

 

"someone tried explaining all of that to you about 300 posts ago. you should listen to just about everyone that has posted. we arent trying to steer you in the wrong direction. this all started because you were giving g5 owners **** that they didnt deserve."

end quote, dr phil

 

"The GM Stage 1 tune raises the Desired Boost and Actual Torque output levels but does NOT completely remove the learn down but it does raise it. Other Tunes work the same way. They do not completely remove the learn down they merely raise it to a level that the car cannot acheive in the first place. Think of the learn down more like a target airload level or target torque output level. If you add mods or change the charge air density the ECM will sense that it is reaching its target torque output much more easily than before."

 

There you go!

 

Good news to me. Looks like I will be close to 295 on paper. Looking foward to a chance to dyno it and see what that means in the wheels.
