GM = warranty
CA = none

 

ok thats 1 difference..thanks

 

deff the gm stage2... just my .02 with better tune

 

go with the GM unless your not under warranty and you really dont care what happens...

safely i wouldn't go below a 2.9" pulley

 

yeah i think i will go with the gm stage 2... thanks fyi

 

I'm pretty sure the CA kit comes with 60 lbers instead of the 42's. They just never changed the site. I think.
If you don't care about warranty then go with the CA kit. Much better than the GM kit.

 

Go with GM, I did and I love how the car runs now, it's under warranty still and I know its good quality stuff that the car and supercharger can handle no problem.

 

GMP Stage II is the way to go!

 

Doesn't crate engine depot have the S2 for 550?

 

get the parts from C/A and I"ll take care of the tuning.... if not I can still pull another 20+hp outta the gm stage II setup

 

It really depends on what you want out of the car or if you care about warranty.

 

Holy crap, i didn't know that was possible with that setup. Is it still safe?

 

Gm..

 

puts the injectors in the high duty cyle area, but so far I have a bunch of guys running around with that setup with no issues.... as long as you don't spend extended periods of time above 6000 rpm it's fine (still do occasional blasts to 7200 rpm though)

 

I'm the only one in my area thats on this site. I've been thinking about maybe getting the hp tuners software and help out my fellow cobalt owners here. The problem is that every time I try to get their attention they they want to race me and look at me in disgust. If I were to go through with this would you give me some advice?

 

yeah no problem. and I have the same problem out here too... everytime I pull up to one they all think I'm trying to race, and trust me, my cobalt is not one you want to try and run stock or not

 

sir,does ur cobalt even work?hahahaha

so u recommend the gm s2 or the addictation kit s2?

 

cobalt always works.... cept when it's broken..lol. but it's never been down for more than a day or two. But I don't really like the gm stuff anyway, the tune is weak, the injectors don't flow as much as the lucas 42s. I'd go with the C/A stuff and get a custom tune.... which I do on the side lol

 

yeah i love my warranty so i think im goin to go with the gm stage 2 ....hey black if you retune my gm tune would it void warranty basically would they now i retuned it after them...how would the tune be like...harsh or safe?

 

im stock right now but i remember when i met you , u sed u can tune my car .. how much would it cost anyway because im kind of interested

 

i think he said 100 bux and get a couple HOT chicks to pose for his car and sleep with him for cpl days

 

That sounds resonable, and do able.

 

lol.... for a few hot chick (not under age though as I am a bit older lol) and $100 it can be done.
Or $150 and we'll call it a deal. Just need to let me know at least a day in advance so I can get some more credits... burned through 22 so far (at $49 a pc.. ouch)

 

haha alrite man ill let u know some time next week
