I have a 2006 cobalt ss/sc.. I currently have a injen c.a.i and magnaflow exhaust making about 14 and half to 15 lbs of boost.. I want to go to stage 2 but im not sure what i need or where to to get it tuned. Can someone help me with what i need to do or where i could get a tune perferably a dyno tune??

 

If you're getting a Stage 2, OTTP, GM Stage 2, & ZZP all offer tunes or a new PCM with their stage kits. All tuned (usually not always) correctly for the parts you're putting in.

Some times minimal tuning is required after wards.

 

You're not making 14.5-15 lbs of boost on the stock pulley.

You need to research all of the available stage 2 options (GM, ZZP, OTTP, CA, etc.), and decide which suits your goals best.

 

If I buy a stage 2 kit from zzp can I send them my stock ecu for them to flash so it will run with the stage kit??

 

I think you might need a new cat. Your boost shouldn't be that high

 

Yes, you can do that.

 

I bought the car off a buddy of mine and he had put the magnaflow exhaust on it but he took the high flow cat off and put the stock cat back on, so would that be making the boost higher?

 

Would I still need a dyno tune for max power out of the stage kit

 

yes you should still get tuned and like everyone said you cant boost that much on a stock pulley you either have a clogged cat or you already have stage 2

 

yea, how could i check to see if it is already stage two cuz it looks stock and the guy before said he never staged it, although he did put a chip on it for a while

 

he didnt know what he was talking about then.

there are no "chips" for the ss/sc.

 

Thats what i told him, ive looked many times and never found anything.. but i really do want to stage 2 my car, whats the best setup??
im still new with superchargers and im not sure what all to do to make sure it dont blow on me.. for example, whats a core charge on zzp? is tht the ecu

 

look at pulley to see if it pressed on or if it has blue bolts holding it on

 

It looks like its pressed on I don't see any bolts on the supercharger pully.. what does that mean?

 

its there was bolts it would mean u would have aftermarket smaller pulley or stage 2 pulley so if ur stock. Your stock downpipe is probably clogged which is why ur seeing such high psi.

 

I was gonna order a down pipe what's a good brand

 

ZZP Downpipe. Just added the 3 inch catless to mine. Definately worth the money plus it bolts up to a stock system. Not sure what you are but ZZP has my vote.

Look on your pulley for any numbers as well like 79 or 76mm. Numbers like 2.6 to 2.9 might be on it as well. And your pulley is what controls your boost.

 

zzp is great for price but i went with vibrant header/dp

 

On stage 2 do you need a dual pass intercooler plate??
and should i get a zzp heat exchanger?? also what size pulley do u run on stage 2?

 

3inch intake,42's, nates 2.9, s3 h/E, vibrant header and exhaust and a zzp pcm tune till you find a tuner to fine tune it. To me thats a true stage 2 anything else and you just wish you woulda saved your money.

 

which stage 2 are you refering to? gm stage 2 or ottp/zzp stage 2? If you plan on going stage 2 as in 2.8/60 injectors, i suggest a heat exchanger from zzp or ottp AND a meth injection kit. The meth kit is amazing when it comes to the cobalt. Like the pulley and injectors, the meth will require a tune, i highly recommend a dyno tune for that.

 

can zzp send me a already tuned pcm??
and on the zzp options should i get a oversized tensior or a gm shortened belt and do i need a dual pass intercooler plate

 

^this

 

Yes they can send you an already tuned pcm.
Get the shorter belt
You don't need a dual pass just get an heat exchanger

Zzp and ottp has the kits and everything you need

 

when i get a h/e do I i just replace the stock one?
