wow, do u have a car lift and air guns?? i can't imagine getting underneath car and turning off bolts, i mean don't u have to drop the crossmember to get to the dP?? AND the intake only takes you less than 30 min??!! bro u should be a mechanic

 

haha all it is is just a few nuts and bolts, honestly tho I would rather have a really good tune so If anything goes wrong Ill know its because of the tune so then the dealers can fix it for free, that way I can make some money back from them when I paid retail for my car

 

GM kit + warranty is the way to go.

 

Like i said, to each of his own, I got trifecta tune which im switching over to terminator or superman soon and Ill still have warranty, im desperate for power yet need my warranty also so I dont mind an hour or two slapping the stockers back on. Who gives a **** if I dont deserve getting it fixed, the dealers rip ppl of on daily basis.

 

when i said that the GM kit is the way to go that is just my opinion. Personaly i would like a more mild tune.

 

oh alrite thats kool, didnt mean to sound so hostile

 

im not ragging on you or anything. i just think that this is one of those things. one is not better than the other, it just a matter of what you want.

 

I hear you, I just prefer something a little beafier than a stage one, just feel its not enough for $600

 

How about the trifecta gms1 tune made to work with the oem sensors?

 

Get the trifecta switchable tune and ur good to go, gms1 for 600 bucks is way too much for their measly hp add. Idk where you guys are from worrying about ur warranty so much but around here the dealers didnt notice squat on my car, for all I know they prolly thought it was supercharged the whole time.

 

I run into a lot of questions when debating what tune to get...I want to get the trifecta but I would like to know a little more about it before I proceed to buy one. Do I just hook it up and its just a programmer? Also can it be easily unprogrammed? How does the stock clutch hold up on it? Also if I were to get intake would that work with it as well? Last question is has anyone had many problems with the tune that has affected the engine or transmission?
Thanks a lot sam

 

Get the GM stage tune. Trust me on that. I am not going to list the reasons because some Trifecta nutswinger will come in here and try to debate and I am not in the mood for that anymore.

 

But...you're clearly not running the GMS1. I'd be curious to hear your reasoning .

 

For about $600 you can get used catless dp and an intake and boost piping that will get you around 320whp with a proper tune, not just trifecta, im not gonna nutswing on trifectas behalf just in general gms1 is too expensive idk what kind of money you make but personally on my behalf I have to work a week and a half to make 600. Although I can see the gms1 being an update to the stock tune in a way because it can eliminate future knocks or w.e. the gm techs found wrong with the stock tune. The choice is yours, I personally laid out the facts for you on the table not forcing you to go with an aftermarket tune. Just my .02.

 

Rich A/F mixture that this GDI motor is not designed to run sums it up.

 

Your last point is one of the reasons I went GMS1 . I wanted a little more power but right now am not ready to go so far as a second ECM and custom tune. That's not saying I'd NEVER go that route (my friend has one turned with HP Tuners, it's ridiculous how much power that bastard is putting out!), but right now the GMS1 seemed like a good option.

But as for the update to the stock tune, having installed it last Thursday I'd say off-hand they ironed out what I always felt was "wrong" with stock. Third gear in particular always felt flat to me, what do I mean by flat, I'm not sure. It's almost like I was at full boost around 2500rpm but it felt like I was dragging my ass until 3500-3700 or so. With the GMS1 that hesitation is gone and all the gears (within reason) have a feel more in line with what I'd expect with the gear ratios. I intend to write a review of it when I have some time but overall I'm extremely happy with my purchase.

That said, I'll still get my ass handed to me in a bag by a custom tuned TC

Can that not be ironed out with further tuning? The tune should be able to adapt to the AFR required by DI motors by modifying the air flow no?

 

Awesome I always wondered how much better the gms1 is compared to the stock tune, for all we know a gms1 can offer smoother driving experience over an aftermarket tune nevermind the hp/tq.

 

Yes but he commands a 11.7-12.1 A/F. I dunno why but for some reason he tunes them that rich. Quite a few have had issues with misfires and a few cracked pistons.

 

That could definitely explain some of the failures creeping up on the site where overboost didn't always seem to lend itself to the damage. Ouch.

 

Yes. If you search you will find the info you seek. BYT has been overboosting his car for longer than anyone on here and he has had zero issues with it. Cardilino18 (sp), PT5457Balt ( sp) and a couple others have had the same issues.

 

At least the OP has some good opinions to go off of now .

 

So how many people have had problems with just running the trifecta tune? like engine wise? Also are there like different modes i can program it? like a really competitive tune and the a like moderate one or is that not an option? Also is it on a programmer?

 

term have you seen one of vinces newer tunes since the infamous issue you always bring up?

 

Yep, he is still running them rich up top. I know most would think this is safer but what is safe is way different with this GDI engine. In order to come to terms with what is safe and proper and what makes the best power you most toss out everything you know of convention FI engines. Just like carburators and SMPEFI, GDI has a point at which it is just hosing the cylinders down with unneeded excess gasoline. GM runs the stock tune at an amazing 14.0-13.8 A/F at WOT from 2000 rpms to 4500 rpms where it tapers to 13.0-12.9.If you did that to an LSJ you would melt the pistons or shatter them due to rediculous knock. Understand the design of the motor before you get lost in other people's ideas. Do your own reasearch about GDI turbo engines and see what you learn.

 

I'm not questioning your knowledge Term just wondering. I havent heard of any problems/issues witht the newer Trifect switchblade tunes is this true? Also the guys that cracked pistons weren't they running some pretty high boost. I was looking at getting a moderate tune 20-22 Psi do you think I have to worry about cracking a piston?
