I am trying to decide if nitrous is the best way to go for an increase in hp. I have a 2007 mn6 with Corsa sports, xpipe and vararam. I live in Denver and I want to make up for the lost hp due to the high altitude. I do use the car as a daily driver, so I want it to be reliable. I do not race at the track. As far as headers go, I have been told they would cause the car to fail emissions, so that is not an option. So, I thought that nitrous might be the best bang for the buck. I would consider the minimum shot for occasional use. Where do I start? I don't know a thing about nitrous. thanks.

You have a lot to learn (and there are many people who "know it all" and lots of misconceptions.) It's great bang-for-buck! From my experience stock engines seem to respond well to it, as long as you keep it safe. Spend the money on a good NX wet kit (with the safety stuff), have it professionally installed and TUNED on a dyno, and you'll have no issues. I'm waiting on warranty work on my C6, but I sprayed my C5Z like crazy and it loved every minute of it. Relatively stock when I wanted, and noticably quicker on the bottle! Dyno #s in sig...
I don't mind answering any questions, but I surely don't have the time (nor would you likely want to read it!) if I hammered it all out here. When set up properly, it's perfectly safe and reliable. I've never had any issues, you just need to be aware of what's going on and be able to pay attention if something doesn't seem right.

Nitrous is A LOT of fun!! I have a TNT wet kit on my car and the kick in the arse is just wow. It's not very expensive to get a good kit, not very expensive to install, and for the money I dont think anything else can give you more power. It does have its downsides though. You have to make sure you have enough nitrous to begin with, otherwise no good. Hiding the bottle is a pain in the ass, unless you dont mind bein able to see it. You MUST make sure your traction control is off if you are going to use it. And again, havin to refill bottles sucks. Other than those things though.......ooooooh u'll love it.
The biggest thing with nitrous is make sure your air-to-fuel ratio is correct (via a proper computerized tune). It's the key to being safe. You're adding extra oxygen via nitrous. Gotta make sure you're adding extra fuel as well or you could burn a piston. Also, like others have said, keep the shot small (at least to start). That said, nitrous is great power adder. You have the advantage of keeping everything stock until you want the power, presumably infrequently since you have to refill the bottle. Also, purge kits are fun on the street and intimidating to others. Compare this to superchargers, which are always on. Both power adders have their advantages and disadvantages... I like 'em both!

I prefer wet systems due to tuning abilities and adjustability. 100-150 shot should be fine. I will be most likely running the same 125 shot as I did on my Z. If anything I'm told the bottom ends on the LS2 are as stong/or stronger than the LS6, so should be perfectly safe if tuned and setup/installed properly. I wouldn't run more than a 100 shot dry (and by doing that you are at the mercy of the stock MAF and PCM for riching up the mixture.)

You're fine up to a 125 shot wet. If you go 150 or more you will probably need to run higher octane fuel. I'm currently running a TNT kit with a 150 shot on my heads/cam car. The kick from the wet shot feels sooooooooo awesome. I am thinking of switching to dry though because im always worried of a backfire with wet kits.

If you are using a window switch on your wet setup (as you should) and have it set properly, you won't have any issues with backfires. Set it from 3k RPMs to just before redline and you'll have no issues.
Thats what how I have it setup. Backfires are not too common, but they do happen. I have seen it happen even with the window switch in place. Maybe I'm just chicken-sh!t, lol.

If you use a microthrottle switch and a window switch I don't see how nor have never heard of anyone having a nitrous backfire.
Nitrous backfires are caused by fuel and nitrous puddling in the intake (generally dry intakes are much more prone to this, as they aren't designed for fuel to be dumped into them.) At WOT and above 3k RPMs, there is PLENTY of vacuum going into the cylinders to prevent this from happening. IF you are NOT at WOT and/or at too low of an RPM this can easily happen. As long as you have the RPMs and throttle open (creating pull and flow into the engine) a nitrous backfire will not be an issue.
Bottom line: always use a microthrottle switch and a window swith with a wet system, set the RPM range properly and throttle switch, and you'll be fine.
