I was thinking about ordering this, but i read that it disables your air conditioning while the pcm is plugged in.. not to happy about that living in flordia lol. Is there a work around for this yet, like a chip u can put in between your computer and the pcm to block it from reprograming the air conditioning. Otherwise when u stop at a light next to that weak mustang u wanna race, u have do a chinese fire drill to plug the thing in.... thats just not cool hah.
btw im new here, we ( girlfriend and myself) have 2 cobalt ss '07, http://www.evolution2kx.com/~xnigelx/car.html <-- mine brand new so far ive only tinted it and i just ordered my stage two from gm. My girlfriend has essentially the same car but blue.

 

nope no a/c... unless you can go into via hp tuners and change it... but since I have no a/c in my car anyway.... It's no big deal..

and by the way I usually remove the a/c on all my cars... just for that extra little edge.. and plus ... well I can take the heat..

 

First off, welcome to the site (both of you)! As for the Stage 3, I'm not 100% sure, but you could disable that portion by using HPTuners. In my opinion, making your own "Stage Kit" would be the better way to go. Just get yourself a pulley, injectors, smaller belt, and a custom tune. Thats just my opinion though, I'm sure someone can get you a better answer with the Stage 3 a/c thing.

 

well new york has a bit diffrent temp zone than flordia.. seeing as how tis what 20-40 degrees by you (im from chicago so i know) and tis 80 down here hahaha..

 

yeah but it does get into the upper 90's in the summer.... hit 105 a couple time last summer... so yeah it gets damn hot up here too.... and really ****** cold.

 

thank you

i was thinking that but im trying to keep my warrenty so im gonna do everything gm for now anyhow. im pretty impress with this car, i raced a c4 corvette the other day granted it wasnt a special one or anythign and it was automatic, but still 8cly vs 4... the guy was banging his head off his steering wheel... i sapose i would have too

 

Seriously man the Stage 2 is kinda not what you are going to expect. It is a noticeable difference but for the same money or really even less you can probably put down more than what the S2 + S3 will yield. Just my .02

p.s.- in the south you gotta have a/c!!!

 

hahaha 105 in the summer for flordia is cool from what im told... i think ill get the stage 3 and leave it unplugged on those hot days..

off topic has anyone tested the two exhaust systems from GM? im curious on how the two sound... if it sound like a dirt bike im not gonna bother.

 

search that, I'm sure you can find several sound clips

 

IT is true that you can get more power out of stage kits other than GM, but unles you have $4000 laying around to replace the motor when it blows up and GM says to your warranty, you are better off with the stage 2. I have an 06 ss/sc with GM stage 2, GM stage 3 pulley, and an AEM cold air intake and I love it. You should buy the stage 3 pulley and have them install that.

 

excellent ill chek it out

 

Actaully the Stage 3 isn't covered under warranty, it is for "off-road use only". You would have to go with the Stage 2 to keep the warrenty. And like said above, it will be noticeable, but you can get better performance gains for less by making your own kit, granted you will lose your warranty though. Also, I have the GMMP Performance exhaust and I love it, a lot of people have it and would agree.

 

I've got a 2.8 and going to install 60s as soon as they get here. A safe tune and no real radical mods you should be fine.

 

ill definately look into that. If ya dont mind, how much u pay for your stage 2? i paid 640 which i thought was a good deal for a 750 list.... im just curious on how much they will go down when i get one for the other cobalt

 

we had 31 consecutive days of temps over 100 last summer. no ac is a dealbreaker. altho i really only used it when it was over 105. other than that i had the windows down. hell it was 83 two days ago. my 65 doesnt have ac, but i still dont have it up and running. maybe tomorrow.

 

well as logn as the exhaust doesnt sound like a kawasiki dirt bike.. im coming from a old camaro so i love the rumble sound of a v8, obviously i cant reproduce that on a 4cly but id like to get sound similar to it.. i jsut dont want a fast and furious rice car sound.

 

x2. It can easily be done safely.

 

u just got snow the other day didnt you? haha i never thought it would snow in TX.. my girlfriend is from dallas

 

Yea, the GMPP exhaust systems both sound nice and have gotten great reviews from members here, myself included. Sounds like you would probably like the touring better, its a little deeper than the performance one.

 

cool, ill check out the sound clips a lil later when i feel like running a search. other than exhaust and stage kits what else can i get from GM to increase the performance on this car? Id like to get it as high as possible while keeping the warrenty

 

What I paid for mine is irrelevant. I manage a collision center and purchse over $60,000 a year in parts from Chevy alone. I got my stage 2 kit for $480. Installed for free and paid $18000 for my car out the door.

 

ok well i have to get going, gotta pick up the new car today. ill see you guys later im sure, and thank your for the info.

 

good luck with your choices man they are hard to make!

 

wow lucky
