no not yet, just got finished paying off my gmpp clutch. lol and i heard they are out of stock on some things, so when i do order, i'll probably have to wait a while. i might get it on the credit card in a couple weeks, but im the kind of person that doesn't like building up debt. lol

okay, I just put a new boost gauge in today and I found out that my stock one wasn't very accurate. this one is telling me that i'm running about 13 max psi. and that's running it as hard as it goes.

Not trying to hijack your thread here but I feel that we have similar topics so hopefully you don't mind. I bought what I thought was a stock cobalt ss 2 weeks ago, but now I think it may have some aftermarket parts (my pulley does not look like the one in the picture). It is stamped 77.9 mm which is about 3 inches. This to my knowledge is smaller than stock correct? here is a picture of the pulley (which is terrible, my camera won't fit in there so I had to use my phone)
Now, I had no plans to modify the car and was just going to leave it stock. But now I am curious, would a 3 inch pulley require new injectors? I just kind of want to know what parts my car has under the hood. Is this the gmpp stage 2 kit? and finally how much power would you estimate I would be making with the smaller pulley? this is the only mod I have noticed on the car, it has the stock airbox, and exhaust.

car seems to run fine, there is no check engine light or anything. what would happen if the injectors were not upgraded (I've been looking into it and I think this is the gmpp stage 2 kit so I think they are)?
I've gotten on the gas once or twice since I've had the car and everything seemed fine, so I think I am ok.

idk about other brands put OTTP stage 2 pulley is 2.8". The one that you say that you have is 3.01". I would say it's a stage 1. OTTP has a stage 1 kit that has a 3" pulley. that's what I'd say you got. It may not be OTTP but I'm pretty sure that it's the stage 1.
