OMG what a difference!!! the whine is so much louder so much more power my face has been like this the whole time ive been driving it 
definatly a BIG change from just the stage 1. Now all Im gonna do for the rest is header dp combo and im gonna be done modding for a bit. and may be a cobra h/e and an hp tune later down the road. but as of right now Im happy

nice, im getting ready to do the same thing. I am going with the gm stage 2 kit, and full exhaust, cai, and the 2.9 pulley, along with motor/trans mounts. Right now I am 100% stock, but then again i have only had the car for like a week haha.
Nice, it looks like the temps didn't rise much then, thats a good thing. I was wondering if I was going to need any cooling mods, guess not.

I'd look for a HP tuner a.s.ap., and larger injectors if your still on stock ones. I'm running a 2.9 and 42.5 injectors with a IDC above 100% at WOT. Hopefully a AFR tune when my wideband comes in will solve that, if not 60s here I come!
Your IAT2s should remaining around 90-120 cruisin, 120-150 WOT with a 2.9. Though those numbers are variable and depends on your car and how aggressive your tune is, as every car is a freak in its own way.
Before continuing with any performance mods, look into tuning your AFR, you may be leaning out to much on that stage 1 tune with your modified airbox. (I am unfortunately, AFR tuning soon ftw)
May I recommend you the CA 1" Traction bars to obliterate our cars nasty wheel hop. Why make power when you can't use it? One of my favorite purchases.
I'm no genius, nor do I really know how to work on cars. But it seems your heading the same route myself and many others have taken with the 2.9 setup.
GL!
Btw, when you get that flux capacitor, let me know, maybe we can arrange a group buy and all be able to generate 100,000 gigawatts!?!

If you have the stock injectors, they hate you. If you follow your plans you said above, you will love it if you change injectors. I have full exhaust, s2,2.9, and airbox mod and looveeee it for now. I am sure I will do a major upgrade soon though.

I loved the 2.9 when I had it.
Really felt like a whole new car.
Concensus at the time though was the the 2.9 maxed the 42 lb'ers.
I never verified it, but it might be something to keep in mind.
Glad your happy with it! That smile will stick around for a while!
