The first runs were done with no NOS off of the line because I wasn't sure what to expect.So I decided to pull out 2 plugs which they both seem to be a bit lean.That jetting was .52 NOS .32 Fuel so I put in a .35 fuel and finally started leaving on the NOS.

Yep, I keep tellin' people these stock fuel systems will do more than they think. Some folks think it's maxed out with heads/cam running NA. ![Rolleyes](https://ls1tech.com/forums/images/smilies/LS1Tech/rolleyes.gif)
Sweet times and killer MPH.

I for one am surprised the stock fuel system is keepin up on the dope. In the pic below you can see what happened to a firends car with heads/cam and a 125 shot when the fuel pump couldn't keep up

4mulaJoe, did he have a fuel pressure gage? Dry shot or wet?
With any nitrous setup, it's best to start with the small pills and work your way up one step at a time while carefully Autotapping along the way. By doing this you should be able to catch it starting to run lean before it's too late. A fuel pressure gage is also a very good idea in any high HP or power adder setup.

With an M6 (more efficient drivetrain) in a 98 or an '01-'02, I can see maybe 550 RWHP (it's been done before.) 570 is certainly pushing it though!
I wouldn't have tried that without some careful testing to confirm that it would work, such as what I described in my last post.

Nah, different pumps too. Don't ask me why. I don't see why they need injectors or pumps as big as what they have in any year to support stock power levels...but I'm glad they come that way. I'm making roughly 425 RWHP and I'm not even thinking about the fuel system at this point.
<----to GM for the fuel systems.
