Maybe that would make it into Corvette Fever magazine. 
What do most ls3's baseline?

I've read your post before and like I told the other gentleman who's number were very low, he got a bad reading. In your case your numbers are very high and you also have a bad reading. It is obvious, ls2's and 3's and 7's lose 55 in the manual and 65 in the auto and the ZR1 loses 65-67. To think you have the only car in the world that lost 7 hp in the drivetrain is silly. I've asked you to post dyno sheets to no avail. The numbers sound good for bragging rights however I don't think they are good readings. There is no way in hell you hit 429 on a dynojet unless the numbers are bad. At 429 your car should run 11.5 in the 1/4 mile on runflats. Do you have a time slip to show us?

In my experience you can and will see different numbers from the same car on the same dyno, day to day. There are a lot of factors that contribute to this. Once different cars and different dynos at different locations come into play, then it becomes really diluted. Not to mention dyno operators who inflate/deflate numbers knowingly or not.
The goal is to make a change and make many runs to see if the change added performance. This is why a baseline is soo important. As long as a car shows consistent gains over a baseline, the change is good.

Why did you make 5 pulls? As a tool to tune, you would hope for a HP increase, not consistancy. If you didn't make any tuning changes between pulls, what was the purpose?

I assume mods and a previous tune, what are they?
I had good mid-range improvements and picked up nearly 15 hp around 4500 and 9 at 6500. Gained some on torque and flattened the curve. I had a bad dip which is now gone.

I just got my '08 a6 pace car yesterday. I want to at least get a tune and maybe a stage I at MTI. They did a stage I on my '05 mn6 coupe and I really liked the improvements. My '05 had a rwhp baseline of 334 and 389 rwhp after the stage I. What can I expect with my ls3 a6?.......thanks
365/358 stock will be posting actual dyno slip of before and after. Adding Kooks header/cats and Vararam with tune today.

Tuner stated that the mustang dyno runs about 8% below a dynojet.

You are typically 15-16 hp lower than a dynojet for a m6. Your mods should pick up 35-40. I'm guessing 400-405 on the new mustang dyno pull. Good luck and let us know what you get.

So recently I had mine in the shop for the headers and tune and I ended up with 394 rwhp and 393 lb/ft torque and honestly I felt that was a little low. My tuner said it was about right and mentioned the tune was not aggressive b/c he didn't want lots of wear on the engine. Only mods I have are the Vararam (which shows nothing on a dyno), AR headers, B&B Bullets, and the tune.
I looked on the forums and i see these people with 430 rwhp on the same mods and I feel like most of the seem way too high but then again I am no gear head / dyno tuner guru. I mean how aggressive of a tune do these folks have to get these #'s?
