Default Anything wrong w/ this?

Click the image to open in full size.

My dyno doesn't look anything like anyone else I've seen before. It's very up and down. And that's after a tune by Nelson Performance. Could anyone recommend something?

So it's not showin' up? Hmm, it's working fine for me. What is this valve float? Can it hurt my engine and how do I fix it?

no its not valve float, its happening throughout the whole powerband not just up high. valve float is when your cam opens your valves too hard/quickly and the springs can't control them.

it can be bad, i'm pretty sure you can float your valves into your pistons and its also probably hard on the springs themselves. i really doubt you have valve float on a stock cam a4. check out the new numbers in my sig, just got tuned today.

They could turn the smoothing up to 5 and your dyno would look more normal.
