Dyno tune numbers??
I have a 2007 A6 ,I currently have TSP long tube headers and a TSP 224/224 .600 114LSA cam. Took my car to get tuned and pulled 387 whp and 372 ftlb . I see people on YouTube pulling 380-390 with an LS2 CAI, long tubes, with no cam. Do the numbers I got sound correct for the mods listed?? Please give advice!

I have to agree. If no before you really have no idea on actual gains. These motors are not consistent on power output, close but different.

My dyno was in my butt, as it felt like a different car, pulled much harder. My numbers were disappointing like you said but I KNOW ITS CONSIDERABLY FASTER.
I have testimony from other members that have the same mods to the T, DynoJet dyno showed right at 404-408 RWHP while the DynoDynamics showed just what mine did, 364 RWHP and although not same day, same tuner, I believe it holds true to a certain degree.
We wont even bring up the difference in the "sound", that alone makes it faster

its just a number ..... and that number can be different between day by day and in some cases hour by hour
the true measurement is at the track ... what does the time slip say and what MPH and I can tell you, you can get pretty close to what the motor is producing for real with just those two numbers

But as you've said (and I agree)...who cares....if you're looking for personal satisfaction - the sound - the feel - knowing that YOU did the wrenching and that you've learned so much in the process....unless you're drag race dedicated, who cares, but look at how much you've gained! Beautiful car, sounds/feels great, and you're a genuine advisor now for all these newbees wanting to do headers...

Yeah Bobby, you really needed a baseline readout. In your case, you DIYed the install, then dynoed, so you cannot know the actual gain.

Personally I like lower dyno number so people get confused when the lower horse power car is faster. Take it to the track and see what it traps. That'll give you a better idea how the car is running.

The same day? How are you supposed to achieve that when you put a cam, exhaust and heads on your car? That part of your statement is very extreme. Using the same dyno gets you pretty much the results you need to find the differences in go fast parts.

As long as before/after runs are on the same dyno and have generally the same atmospheric conditions (temps/humidity/air pressure), the before/after comparison will have merit. Same conditions can often (not always) be pretty much replicated if the dyno runs are conducted at about the same time of day aon different days.
Hell.....atmospheric conditions can change significantly in the course of a couple of hours.....
