NEED HELP! nitrous on an LS3

I just bought a wet nitrous kit for my camaro, I am only running a 50 shot and I was wondering if I had to adjust my ignition timing to run such a low shot. If so how and what is the best way? Thanks so much for your advice!

Do NOT run nitrous without a proper tune done by someone who knows what he is doing. If you run lean, you destroy your engine. Got a spare ten Gs lying around?

Where are you? Someone on here will know a decent shop you can have tune your car.
300-500 is usually the going rate.

Usually with nitrous, a 50-75 shot without tuning is fine on a stock engine or an engine with bolt-ons. You have a 50 shot so you shouldn't have any problems. If you have an aftermarket cam or boost or other extensive mods done, then you will need someone to look at it. Just make sure the install is correct. And it never hurts to contact a performance shop for advice.

Thanks for the advice, I heard that if i stay at 75 or below I would be ok, I just want to make sure I don't have to retard the timing , book that came with the kit said 2 degrees but the 58x ignition system on the camaro should adjust itself?

Yea rule of thumb is 2 degree retard for every 50 hp on a V8 engine. But like I said, lots of people get away with 50-75 and no tuning. But you also have to be safe. Just because some people get away with it doesn't mean you will also. So if you are any bit unsure, then contact a few speed shops for their advice.
