That sounds about right. I did a before and after dyno on my car. When I first got my car it was as stock as you could get, and i took it to the local dyno so I could see how much power I had to start from. Bone stock with a 4l60e it made 278 @ the tire. So with a cam only, if you made 336 rwhp you picked up a good bit of power. Thats over 50 rwhp.

Ill try and answer all the questions as best I can. This is the first time Ive ever done any mods like this...first time Ive ever had anything on a dyno even. By the way, I was not the one operating the car during the dyno runs. OK. Here goes.
Redline Performance in Herculaneum MO did the tune.
I don't know why the chart starts over 5000 rpm. I honestly don't know where it should start. The stall is a Yank 3800 and I have 3:73 gears. Don't know if it was locked or unlocked. How can you tell the difference?
Not sure what the rev limiter is set at but the pull was stopped at 6600 rpm.
Im guessing they pulled it in 3rd gear???
Shouldn't the hp curve look different than that? I was expecting more of a jump at the beginning (like almost straight up), then level off w/ a gradual rise, and then peter off right at the end.

I bet the pull was made in the wrong gear and the stall wasn't locked up as well. Is that shop a sponsor on this board? Do they have LSx experience? call and ask if the guy in the car happened to be looking at the speedometer, that should tell you what gear you are in. Take it to the track and see what's really up if everything else seems to check out.
Good Luck
