Is there still no tune for the E37?

I realize that there is that ls2edit thing, but I'm not going to be able to do it.

Where would I have to take it?

Halfcent

To a tuner shop that does have it.

Has anyone used a SMT6 piggy system before?

i was reading up on the smt6 fmu and its pretty much the same as the aem p/i controller plus it is already made for our cars plus if you go with custom tune get it from trifecta and if your going to push 250 at least change your head gasket at the minimum since most internals can hack 250 hp

I've been doing some searching here and I can't find the answer to my question.

I have a small turbo sitting around that I know would work great on my cobalt, its an 06. I have plenty of parts to put it all together, the plumbing and all that fun stuff should only be a small headache.

Tuning is the biggest problem. I'm not going for any big power numbers, 2-3# of boost is all I'm really looking for. Just some extra power through the mountains and a bit of added fuel economy would make me pretty happy. I'm guessing the stock computer would be able to handle that kind of boost without any problem. Does anyone know anything about that?

What year and model cobalt is it?

06 2.2

Stop and think about that for a moment. Is that really smart? "Oh, it will be okay"

It will not be okay. It will not be able to handle it. As we have seen on this board in the past, people have done what you are proposing. And it worked, at first. And they where very proud that it worked, at first. And then a few thousand miles later, the engine blew.

You need a tune. If you are going to put all the effort into the modification, spend the $500 and get a tune for it.

Sorry, another question. If I got the garrett or the hahn 2.2L kit and took a copy of ls2edit to a tuner shop would that be all I would need? I have an auto tranny, would that need to be tuned or worked on?

Halfcent

You wouldn't want to take a copy of the software to a shop. You want to go to a shop that already has it. That would be like bringing your own food to a restaurant to eat. And yes, the transmission would need a tune as well as the engine.

Sentry

I doubt most shops would have ls2edit, but maybe I'm wrong.

Anyone know any tuning shops in Texas?

well i googled ls2 edit to see what it can do and i found this from a gto forum in case if any one wants to go that route http://www.ls1gto.com/forums/archive.../t-107079.html

what do u think would be more cost effictive and be better for the long run on a 2.2l 2008 Cobalt LT. Dont know to much about this right now. Assuming I have the LSJ engine, would a supercharger, or a turbocharger be more cost effective, and hold up better with mileage. Also, are there any available yet for the LSJ?

Halfcent

I'm confused by your question. You say you have a "2.2l 2008 Cobalt LT", but then you say you have the LSJ engine. That doesn't make sense. Which one do you have?

My mistake, I meant the 2.2l engine. U know what im talking about

You have the 08, which means you have SAI correct? If I'm not mistaken, this means that your headers are different. I'm pretty sure the SAI can be taken off pretty easily, but check first before you go making big plans.

Now, what are your goals for your car? Do you want the versatility of a turbo that can make massive gains for more money? Or, you could go supercharged for a limited amount of power for less money.

Your internals are not going to be happy taking 300 hp if you do slap on a big turbo. After that, you're talking about spending ungodly amounts of time and money trying to upgrade a car that could break at any moment running that amount of power without a good tune.

The supercharger will be cheaper, and put out about the same power as that garrett kit, and you won't really have to worry about breaking anything if you get a proper tune. As long as you keep it under 250 hp, your stock setup will work.

Basically, I'm saying you have two roads. One is the 240-60 max hp range, and the other can be whatever you want it to be, but it will cost you greatly if you go building the head. Make sure you're ready for that kind of monetary commitment.

So ive read this whole thread, and this is what i understand....

-I have an auto 07' G5
-I would like the Garett Alpha kit, but i would need the trifecta tune for it.

Other than that..... thats all i need. Correct?
I get confused with all the different engine types.

Halfcent

That would work, correct.

jlaudiog5

Would it also be cheaper to build my own?

trifecta did a good job tuning my turbo set up. dyno'd at 258.94whp 215.68wtrq @ 10psi

jlaudiog5

very nice. thats about the HP im really looking for. in about the 250 range. the garrett says it only gets you around 200-220ish. whats up with that. is it all in the tune?

xCobalt05x

no, (the tune helps though) there is a lot more too it... it depends on the turbo you are using as well... mainly the cfm rating but there are other factors.

my turbo is a t60-1 hiflow hybrid w/ ceramic ball bearings and it moves 786cfm's

the first tune on my car dyno'd at 242whp and vince at trifecta had me data log the dyno pull's and he saw that he could add more timing so he just kept adding timing until he saw Kr in the data log and then backed the timing down a touch. walla 258whp

I still have issues with the tune uptop but im close to the braking point of the stock rods so im leaving it the way it is till i can get another motor forged.

jlaudiog5

ah, would it be safer to get the garrett kit with a trifecta tune i am assuming?
