Ok everyone, as the title states I have a dilemma.

I have a gm stage 1 kit on the way(which should be here any day now) but I have been thinking about trifecta tuning. I have heard good and bad things about this. Now first off I wouldn't be going with the infiniboost, I would go with the 22-23 psi switchable tune. I'm debating on whether or not to sell the gm stage 1 kit and just go trifecta. The reason I didn't mention hp tuners is because I don't have access to it, nor do I have the time to learn. I know alot are gonna say to keep the stage kit then tune over top of it, but I don't wanna spend the money out for both right now.

If I was to keep the stage kit and get a tune on top of it, it wouldn't be happening for atleast a year. My fear is that I'm not going to be happy with the stage kit and full bolt ons..

I k ow alot of people have had trouble with the infiniboost tune, but has anyone had trouble with the plain switchable tune??

Thanks in advance.

 

GMS1 and ditch your SRI.

 

I know I should ditch the Sri but I love the sound and my car runs fine with it....no datalogging capabilities of course

 

trifecta.....better power gains. if you bought the gms1 because your that worried about warrenty issues you shouldnt be modifying your car to begin with. no offense to by any means its just my personal opinion.

 

why not both?

 

Don't wanna spend the money on both right now

 

that's just an ignorant comment.. why shouldn't be be modifying his car at all? That's the whole point to the factory upgrade kit.. to modify and keep your warranty. I will be purchasing the upgrade soon.. only because I cannot afford to lose my warranty. Do you get better gains for your money with trifecta or HPT? sure... but thats not worth it to me. How much is it gonna cost you when you blow a piston and GM says tough **** to your claim? Of course that doesn't happen to everyone.. but I certainly cannot afford to take that chance. I even already have HP Tuners from my previous vehicle.. it has taken everything I have not to buy the credits and tune it. Once I'm out of warranty though.. its on..

 

its really not an ignorant comment nor did i mean to sound like a dick when i said it. look at it like this. i constantly hear from people that they want to keep their warrenty. ok understandable its a good reason BUT then why add parts to your car that are going to increase hp and tq which further then increase the risk of like you said blowing a piston or frying rings. its a risk regardless. dealers will find ways to void your warrenty if they honestly wanted to. they will just say their gms1 wasent the cause of it. if you run a trifecta stealth tune its only noticeable in competitive mod or traction off mode. there should be no reason at all a dealers operating your car in either mode unless they are beating on it. regardless of it all i believe if you have money to mod your car you should have money to fix what breaks....by all means get what you can fixed under warrenty fi you can but what happens when the warrentys up and you break it?

 

First off, as many times as gm dicks people around, I plan on making every warranty claim I can. They cheat toooooooo many innocent people out of warrenty.

Second. Who said anything about me worrying about warrenty. I didn't buy the gm stage kit with warrenty in mind, I bought it for the new sensors due to a bad Batch of sensors for our cars and because people were having issues with other tunes. More or less I wanted a half decent tune. Nothing to do with warrenty. 9/10 times, when something breaks, I will take the oppertunity to upgrade it.

 

We both live in the same basic area. And all i can say, is unless the dealers down the valley way are any better. Forbes and Oregan's are NOT cool about modding these cars and then asking to have warrenty work done. I had to fight them to get Forbes to replace my cat when it blew up because i had the air box mod done. They said it caused my car to run lean and burn up the cat. I fought them for three days. And my car only had 22,000 KM.

 

The dealer I bought the car from is pretty cool. Bruce gm in Middleton. They replaced my intercooler when I had my dp, charge pipes, intake and I was lowered. They are pretty good

 

Im with you... I love the sound of my Dejon SRI, and have never had an issue with it!

As far as the tune, Id say keep the GMS1...I think youll be suprised how happy you really are with it. It REALLY wakes the car up, it may not be as powerful as other tunes, but it still is very fast. Then once you get used to the power and want more, maybe youll be ready to tune on top

Honestly, I saw an increase of almost 75ft/lbs at the wheels and 40whp....thats no small difference.

 

Wow that's pretty good. I emailed bill and he told me that the gm stage kit doesn't have a learn down and that it should take my mods into account. I would be happy to make 300-320whp and 310-330wtq. That's more than enough for now.

 

If you aren't datalogging, you have no business running an SRI or modified exhaust. You won't throw an error until it's 18% off. A 5% fueling error is massive on a WOT run.

 

Who are you to tell me what I have no business doing... I didn't ask for a lecture on datalogging or anything else....just asking a question about a tune.

Thanks for your input

Besides , I don't have access to hp tuners to be able to datalog. How else could I datalog.

 

some dealers arent bad. the only reason i get away with anything is because i know a dealers master tech who just ignores the fact im tuned. i brought it in their lowered with all my bolt ons and they didnt say much but it wasent in for anything performance wise. i was having a failure with 2 of the stock continental tires and the rear brakes were shot. like i said i apologize if i came across as a dick with my comment but i didnt intend too. just im tired of the young punks(general statement not directed twords anyone) that own these cars that wanna keep their warrenty but then they wanna beat the living **** out of the car and modify the hell out of it and then expect warrenty work out of it.

 

i say u get gms1, so u have the 3bar sensors, get ur fill of that, keep warrenty, then when ur ready to get the other one, just tune on top of gms1

 

Nah man, it's ok. You didn't come off that way.

Gm stage kit should be here any day

 

Get the GMS1 tune... use those sensors... have fun with it.... and then have a knowledgable tuner with HPT go over it.... I did an HHR SS and he picked up 40 more WHP and 60 more WTQ after I tuned on top of the Stage kit..... just an FYI.

 

Sweet....I was hoping to have yours or terms input. So do you think it will be fine with stage 1 kit and bolt ons until I get a tune on top of the kit?

Thanks

 

An intake sure, but what's wrong with an exhaust? So many people on here have aftermarket DP' or Exhausts without being tuned for them and have no issues.

 

yeah, that should be fine. Hell just install the sensors I have the Cobalt Stage File on my laptop just have someone HPTune it on your car and BLAMO stage kit engaged!


but yes I think you will be fine just get rid of the intake... untill you get it tuned... the higher airflow seems to make the MAF error's evil head to appear much worse!

 

Thanks.....

 

DoMiStIc_RuSh_06 if it makes you feel better I am having the same dilema as you right now lol. GMS1 or Trifecta.

GMS1 = Indisputable warranty and modest power gains

Trifecta = 99% chance of no warranty issues (especially if your like me and planning on getting the cable so as to flash back to stock for any and all dealer visits) and better power gains then GMS1


Leaning heavily towards Trifecta but I've been researching and sitting on the fence with this one for a few months honestly starting to pull my hair out over this one

 

im waiting to flash my GMS1 and i think the power gains from GMS1 + boltons will be more than enough power... i am not trying to be and never will be the fastest cobalt out there and i think a 280-300hp balt is plenty fast enough. just my opinion.
