Well guys I just got back from the shop and I have the stage 2 gm kit installed. My current mods are cat delete, 3 inch custom exhaust with magnaflow muffler and tip with the stage 2 kit. I am currently hitting 1 line above the 15, so I think thats 16.5lbs of boost give or take. Everything else is stock.

At first I had a huge smile on my face and loved the stage 2 kit, and then I almost instantaneously questioned whether or not it was worth it. I feel the difference, but I can't really see the difference ya know. I really think I need to get it on a dyno so I know I have the gains etc.

The redline is now 7k and I hit it once to make sure, The wheel hop kinda turned into wheel spin lol, but all in all its really fun and I am sure when I pull up to the next boosted ricer, I will love it even more.

Just wanted to give you guys my 2 cents and letcha know whats up.

By the way, the 16 1/2 lbs of boost was made at basically sea level in elk grove california.

Thanks for everything guys.

Zach.

PS: I think I am going to get the HPTuners stuff and start doing some custom tunes, soon to come will be headers, downpipe, and some guages, wideband, etc.

 

Congrats, another stage II balt around!

 

I know what you are saying. You just get used to the car, and it seems slow again. That was exactly the way I thought. It was fast at the start, but then slow 3 days later. That is why they say,"Modding is a major addiction!!!"

 

Let us know how the installs go...I have some of the same parts waiting to be installed...no stage II yet though.......

 

So far everything is great, the instant 12lbs of boost is amazing, and the 16lbs of boost max is great. I need to get the wheel hop/spin under control though. What are some good 18inch tires to run on the streets? I am assuming I just need 2 really good front tires, and the stock rear tires will be fine correct?

Also, will I see an increase in boost with headers/downpipe or will it remain the same? I have heard some people saying that I should grab a 2.9inch pulley and put it on. Is this a good idea. If anything bad happens to the car, I can always put the gm stage 2 pulley back on and then take it back to the shop.

So far the only "problem" is I have a CEL because of the cat delete. Since I don't live where there is any smog testing/emissions I decided to delete it and put it in my trunk and sell it haha.

I am heading back towards home, so I will let you know how the gas mileage is, generally i can get slightly over 300 to a tank of gas, hopefully that will remain the same. Again thats with cruise control on the highway.

Thanks for everyones input, and please let me know what other mods I should do in the future etc. Like I said I will probably do headers/dp if its worth it, and rims to look cool, and then cooling mods.

 

A header may actually drop your boost a pound or so dude to less restriction.

I run Stage 2, 2.9, mid-length header, 3" DP, and GMPP cat-back along with a intake. I love the setup I have right now, power is great and I was able to pull a VERY tiny bit on a LS1 trans AM from a 40 roll.

 

How much did yah pay to get it installed?

 

1k out the door after taxes and all of that. It wasn't the cheapest but whatever.
