The question that should be asked is "what do other stock LS3s make on that dyno?"

Some dynos read low and some are overly generous.

Yea I could of guessed that, but luckily I know the difference right? I just wanted to see how my numbers sat to everyone else.

Should I wait until its broken in a bit more before I start adding serious mods like cam or S/C?

I don't think it matters. Might even be better to blow it earlier.

I'm surprised no one thought to say try a fuse pull.

On a Dynojet with only 850 miles I made 366 RWHP with a CAI. At 2400 miles I made 377 HP with the same setup for a baseline pull. My tuner said the LS3 starts to open up right around 2500 miles. Apparently so from my experience.

Go to the track. If you pull about 112mph or more in the traps then your car is fine.

as said before - way to many variables can sway numbers up or down (tire pressure, how the car was strapped down, etc... you'd be surprised) and dyno's aren't comparable from one to another directly.

Dont worry about it and get some track times. When you're running similar times to everyone else it will sink in that numbers... are just numbers sometimes.

Now proceed to dump more money into it to go fast
