I know I've seen a graph that was similiar in appearance, but can't find it. I was wondering if anyone knows the possible reason for the graph not being smooth. My mods are FS race header, Magnaflow cat back, Iceman, and Unorthodox UDP.

I don't think that's what it is. I think it might be his spark plugs? I dunno but something's definately funny there. Here's an overlay I did of my dyno and Ben's dyno. We both did them on the same day, on the same dyno. I have comperable mods minus the race header and exhaust.

Both cars were in 4th gear.. done not 15 minutes apart from each other... on the same dyno, by the same driver. Using the same spark plug wires (focussport).

Where did the shop connect the inductive spark lead to sense your engines RPM? Choppiness like that could be a result of poor ignition pickup for the dyno, maybe there wasn't a good clean ground or possibly their could be a problem with your plug wires.

thats fine, you have to go into the smoothing effect part of the software, and you can slide(dynojet) it from 1-5, 5 being the smoothest
