Ok I bought an 06 ss/sc. Yesterday when I put cai on it had been choped.I also noticed a silver pullie. I don't know if its been reflashed new injector or any thing. when the dealer brought it to me they filled it up with regular gas(boost about 10-12psi).So I ran it out and put primium in and boost goes to 15-17psi.How can I tell if stg2 has been put on right.

 

correct me if i'm wrong, but when i got mine installed the dealer put a reflash sticker next to my gm performance badge under my hood, 15 psi is normal, are you getting any knocking noises under the hood?

 

does the sticker say stage 2? were you charged for it? that's probably the easiest way to tell if you have it. i highly doubt they gave it to you for free.

 

The easiest way is to take your car to redline. If it redlines at 6.5k, you don't have it. If it hits 7k, you have it.

 

If its a bland silver pulley then chances are its a 2.8 pulley if your boosting over 15 psi. Like the previous poster stated, check to see if you hit the rev limiter at 6800 to 7k. If it gets that high then you have a different flash.

 

Is the pully a press on or does it have 5 little allen key bolts holding it on?

 

I think he's saying he bought a used car and the dealer didn't/couldn't tell him squat about it.

I think it has an aftermarket pulley on it since it is silver instead of black and its going above 15 psi. Does the rev limiter show itself at 6500 RPM or higher?

The dealer put my emissions sticker on the bottom edge of the hood instead of next to the performance division badge.

 

shiz didnt even think to tell him that... i got the sticker, it just says reflashed and has a date, i'm thinkin u have nothing to worry about just another tally mark to add to the dealership fu*kups list.

 

the pullley doesnt have any markings or anything??

welcome by the way....

 

not correct .... I have stage 1 and I get 7K redline...
so the 7K redline can mean either stage 1 or 2

stage 1 = 12 psi
stage 2 = 15 psi

 

Aren't stage 1 and 2 the same tune anyway? Either way he still has more because of the silver pulley. Look at the injectors too. If they are green then they are stock.

 

blue bolts holding on the pulley

 

Well I've been seeing people changing out those cheap bolts anyway so can't go on that and be 100% sure. Also it's a silver pulley so that's not a stage 2 pulley there. BTW, is it a modular pulley (bolts holding it on), or a press on?
