I have a 05 ss sc gm stage 2 zzp mid length header zzp 3inch dp to 2.5 also have magnaflow 2.5 catback Injen cold air. Currently am unsure if my balt is tuned because the previous owner did the gm stage 2. I think it might be the stock tune i know if it is its doing nothing but hurting my motor. So my question is could this be why im blowing out cats? I have been threw 2 in the last few months 1st was a vibrant high flow and now a zzp and also one flex pipe.

 

I'm not totally understanding what you're trying to say or ask....

But, the GM stage 2 package comes with a tune. So you are tuned, it's just the GM stage 2. Not a custom one.

 

Sorry had a hiccup with my phone i edited it. Also the guy that had it befor me got the stage 2 used so i doubt it came with a tune.

 

Hmm... does it still have the gm stage 2 injectors and pulley?

 

Yea

 

Okay so what exactly are you trying to ask?

 

Also blowing blackish blue smoke on cold start ups i figure its just running rich on cold starts. Is this correct? Or are my valve guides leakin?

 

Chances are, it's just due to the cold start. Try letting your car idle and get up to temp, shut it off and restart it. See if it happens again.. There's like a 1% chance of your valve seals leaking.

 

Im asking why i cant keep a cat on the car? It blows them out every few months.

 

Maybe it does have the GM stage 2 tune, and you're just running fairly rich.. Because GM stage 2 tunes are pretty rich for safety purposes.. & it's clogging the hell out of your cat

 

I did this and once warm it dosnt smoke. I figured it was just running ritch on cold starts.

 

Yuuuup that's the issue then. Every cobalt does it pretty much.. Well, LSJ at least.

 

And see this is why it sucks getting a car you didnt install the parts yourself. Then you have no idea what the other person did. Now im just guessing if its tuned or not it sucks not knowing for sure.

 

It more than likely has the gm tune

 

Well i should be getting a big check in the mail from a lawsuit this is deff going into a good tune. I live in bfe tn so finding a tuner is hard

 

Go catless problem solved.

 

Yea i know its just so freaking loud with out a cat. I my gf just had a baby yesterday so now i also have a new born thats not going to like the noise.

 

its supposed to be rich on cold start up

 

you would be suprised

 

Yea i was thinking being under boost we would be more prone to valve seals leaking.

 

Chevycobaltss3 is kinda close. Also team Ss is here in Huntsville Al. Im not sure if he is affiliated with trifecta or if he HP tunes though.

 

Get ZZP's resonator. My car is super quiet catless.

 

Whats your exhaust setup? I have bad mab header and then 2.5 zzp dp to 2.5 zzp exhaust and mines pretty loud....

 

Team ss doesn't tune, he does remote tuning through james(ccss3). I would pm chevycobaltss3 on here. I live in tn too, where are you located?
