Looks like the graph smoothing was on 0 or 2, can't read it very well. Look in the upper right corner. It should be set on 5.

What is up with that huge dip when it hits? My bud dynoed also and his wasn't all choppy like mine. So you think everything looks good besides the smoothing thing??

Any mods in here want to give it a shot on telling me why my graph looks like a scrible and why the tq is so low?

You graph looks like 'scribble' because the dyno operater didn't 'smooth' the graph...Don't worry about it.

When did you hit the nitrous? 4000ish?

3000 and I don't think thats why it is scribbled cause the first part of the graph is smooth from being n/a until it hits at 3000

Its scribbly because of what others have already said. Smoothing is on 0. You can go back to the dyno people and have them print you one out with the smoothing on 3 or 4.

If you dont have a purge and if this was your first run that may be the cuase of your soft hit upon activation.

Di you do more than one pull?

that was the third pull and I purged b4 that run and I dont think thats why it is scribble. Why would the n/a portion up to 3000 be nice and smooth?back when the car made 380hp on shot it never dipped or scribbled. all my dyno pulls ever since the car started getting above 400rw would start dipping and getting scribble on 3 different dynos. I appreciate the help man seems like everyone is telling me the same answer so i should just accept thats what it is. The a/f looks good. do noids start to do this if they are maxing out or maybe they are shutting and opening for some reason but I dont feel it when in the car. atap data logs look good. ono knock timing is good. This is a dry kit using powershot noid.

The more power the harder it is to read, especially with a nitrous hit because it can make the tires spin and other things you're not realizing.

How much tire pressure are you running on the dyno? What plugs and what are they gaped at?
